Lawrence fixed my "bass amp problem" (it was actually low battery in upright electric) over the phone. Free of charge. Lawrence is da man! Definitely reccing him to friends and going to him for future amp needs. read more

Lawrence is a diligent and thorough technician. If you want a professional analog tech (and they're very rare these days) who is knowledgeable and seems to truly enjoy his craft, Rance is the place to go. He fixed up my 73 Pro Reverb and a Tascam TSR-8 recorder. He takes time with you and discusses every aspect of the job in thorough detail. read more

Rance is the man. Yes he is not cheap, but do you want your gear to sing or not? My 68 (79?) vibrolux just got cherried out and it sounds divine. Wish I had done this before I recorded but itchng to get it back into the studio! The guy is super thorough and won't even take your stuff until he is ready to turn it around. Two thumbs up!! read more

I felt like Lawrence took a personal interest in my amp project, a little 5 watt Supro from the mid-1960s. I thought it was on its last legs, but Lawrence brought it back from the dead. More important, he did some sleuthing and found the parts that were "working" but causing the amp to under-perform. He replaced those and suggested some mods that turned the amp into an unbelievably powerful little grit machine. I'm really happy with the result. read more

I use the Carvin S 600 stage mate (newest version), for smaller solo gigs. In recent years, it had been cutting out intermittently-Dropped volume or completely out. It could go weeks without showing any problems. That's one of those nightmares for repair guys to deal with: Mysterious intermittent issues. He kept it for a couple of days waiting for the issue to show to diagnose it properly. When finally the problem arose, he traced it, diagnosed it, and fixed it once and for all-Brilliant! I feel very confident in recommending him to anyone + I would feel confident to entrust him with my beloved Soldano, previously owned and modified by George Lynch. He is also a cool cat who clearly articulates complicated (to Me) issues. read more

My go to professional for any analog gear repair. Lawrence is extremely knowledgeable and diligent in his work.

The best analog repair tech I've ever had the pleasure of working with and it's not even close. Lawrence refurbed my TASCAM 38 and troubleshot my 388, both of which work like charms. Skillful, personable and reasonable: A trio of traits I've never come across in this field until Rance Electronics. read more

I have been taking my guitar amps to Rance since 2012 for repairs and tune-ups. He continues to amaze me with his level of knowledge. No matter how obscure the problem is, he will dig in and fix it. Since I started having Rance maintain my amps I have never had one go down on a gig. Plus, he is really nice! read more

Didn't bring my broken Tascam 414 because Rance let me know straight-up if it was worth it or not, i.e. if the repairs would cost more than the purchase itself on Reverb which I was reimbursed for. Super knowledgeable and helpful. read more

Lawrence did a stellar job bringing my old Polytone jazz amp up to speed, upgrading with a new speaker, and replacing the power cord with an IEC plug. Super-clean job, and amp works great. Highly recommended. read more

Brought in my Blues Junior that had what was suspected to be bad filter caps. Lawrence checked it out and found 2 that were bad. Replaced all 4 in a couple of days and did great work and great communication. I'd highly recommend Rance Electronics. read more

Some of you may have had or currently have this issue. I purchased a Marshall DSL 100 many years ago. I only used the amp a few times, as a 100 watt amp is certainly not something you can practice at home with! After purchasing the Boogie Cab Clone (allows one to practice at home using a tube amp with high wattage) I thought I could dust off the Marshall. When I plugged in I noticed the amp was very hot, more than the usual. The problem was incorrect biasing of the amp. Biasing is something I was not equipped to handle. Finding someone to help was difficult. After reading posts of guitarist with the same problem I came across one mentioning Rance Electronics as the place to go for this problem. I contacted Lawrence, felt a good vibe and more importantly he had encountered and resolved the issue many times. That was enough for me. Lawrence was great!....professional, focused and I learned a few thing as well. I dropped off the amp (covid protocols were met) and picked up within a week!! I am ecstatic! I can now use my Marshall and hear that vaunted Marshall sound! I highly recommend Rance Electronics! Peace read more

I always take my guitar and bass amps to Rance. He is thorough, patient, forthright when estimating repair work, and helpful when I have questions. I've gone to a lot of techs over the years and he is one of the best. He's worked on my vintage SVT, Gemini II, and Reeves Custom 225 over the past few years. Highly recommended. read more

Rance has repaired my old 70's SVT for me. He talked me out of new tubes when I did not need them and did quality work. The best thing to do is ask him what his workload is like and then to work out a time to drop off and pick up your equipment. He is frequently busy, so an overnight job can be hard. He did hook me up when it smoked 3 days before a tour once though. Really good guy. read more

Rance appears to no longer exist at this address. The phone also belongs to someone else. As you can see, the reviews are very dated. Hopefully, this will save others time and trouble. read more

Rance did a great job fixing my '97 Matchless Chieftan. Both my bass player and my guitar tech independently referred me to him and for good reason. He may be a little hard to get a hold of sometimes, but keep trying. It's worth it. Solid work. read more

Fixed my Ampeg GU-12 noise issues to perfection. Excellent work performed quickly. Highly recommended. read more

Disclaimer, I just called him and have not yet brought my amp in yet. With that frame of mind, Rance is patient, sounds very knowledgeable, and I very little doubt that he will come through (if its possible). Just wanted to start the review, that's how impressive he was. I'll certainly follow up afterwards. read more

Rance has fixed many things for me over the years and has taught me a great deal about electronics. I wouldn't hesitate for a second to suggest him for any job from simple fix (thanks for troubleshooting the SVT) to complex rebuilds (he completely restored a pair of vintage Telefunken V78s for me). Do not fear. Rance is here! read more

My Marshall Vintage Modern needed a solid tune-up, and I brought it into Rance. I've been playing it for over two months since I got it back, and it is running like an absolute dream. He knows his stuff, is patient and responsive, and absolutely puts the customer first. Plus, his prices are phenomenal considering how much work and know-how he puts in. Five stars, cannot recommend highly enough! read more

As a small update, Rance does repair some digital gear such as my Lexicon reverb unit. So, if you have something like that, it's worth giving him a call and asking if he fixes it. read more

Greg Q is correct that Rance (Lawrence) is no longer at the address on 49th Street, but the phone number (510) 601 6146 is still good. He did a great job repairing the reverb on my old Ampeg tube amp, and I will definitely return if the occasion arises. read more

Very helpful and knowledgeable in helping me get my Tascam TSR-8 fixed after it was damaged during shipping, as well as giving it a general "tune up": making sure the frequency response was flat, alignment, etc. Very nice guy too. read more

I have brought Rance the following items over the last 17 years. 1 SWR Sm-900 amp that blew up. The post Fenders had a habit of Blowing up and its still going strong after being repaired 12 years ago. 1 1961 Bassman Cabinet that needed to be properly rewired. Done with no hassle. 1 1972 Morley Flanger, the big silver box type. Basically ressurected from a shell bought back in the 90's at Black Market Music. 1 Tube Screamer also ressurected. 1 SWR Working Mans 12" combo cleaned and wired. This guy is of the old school hands on craftsmen who make sure the work is done and done well. THE BEST REPAIR GUY IN THE BAY AREA FOR MUSICAL EQUIPMENT BAR NONE. read more

Rance is the man. He knows everything about amps and does great work. Worth the money.

Over the years I have found it incredibly hard to find a quick, reliable, communicative, and knowledgeable service for vintage amp repair in the Bay Area. I contacted Lawrence on recommendation from a friend (who got their '70s SVT serviced) and since going to Rance my Music Man HD-130 has never sounded better. I was so impressed that I brought in my VTM 120 immediately after. In addition to good communication and fair prices, Lawrence's hard work and undeniable craftsmanship has made Rance my go-to for amp repair in the Bay Area read more

Lawrence is no longer at the address listed here but still at the same phone number. I brought him my 1968 Fender Dual Showman which was in very rough shape. He diagnosed tube issues, screwed up ac wiring and a myriad other issues. I wanted to get my amp up and running as best it could so I opted to have him fix all the issues he could find. It was so worth it!! I've got a bunch of vintage Fender amps and this one was the worst sounding when I brought it into Lawrence. Now that he's worked his magic it just might be the best amp I own! I've had work done by a few other techs but would be hard pressed to have any of them look over my amps now that I've seen what a real tech can do for your tone. He keeps you in the loop with your repair and most importantly knows what it takes to make your gear sound better than you even imagined it would. read more

I have been going to Rance for my electronic repairs for more than 10 years. He knows his shit and is a good guy. Highly recommended.

Rance repaired my Trace Elliot amp, and replaced the batteries in both my Mouse amps. His shop was clean and organized. The turnaround time was good given that he was only in the shop a couple of days a week at that time. The repairs have held up fine. I will definitely use his services again if the need arises. read more

Rance did a great job installing power scaling on my 18 watt amp. It works fabulously! Highly recommended.

great work, great turnaround time, fair price. now in Berkeley
