We've been appointed as the area's only qualified BUZZ FEITEN retrofit shop for guitars & basses with the expertise to do these installations properly.If you're picky about your tuning & intonation,check out our Feiten equipped demo guitar for yourself in our shop.If you've already had a Feiten Retrofit done elsewhere that doesn't "feel" right,then we

can re-do it "the right way".

Rainbow Music recognized the need for qualified electronic servicing & repairs back in 1972 when we started out. Our average turnaround (which still amazes most big city customers) is an amazingly quick 3-5 working days (unless your amp is waiting for a rare transistor manufactured in a tiny hovel-plant hidden somewhere in a Honduran rainforest). We are one of the few music shops in the area with a qualified tech-IN-HOUSE.That means we don't send your guitar amp to never-never land for two/three months to get fixed. We have our own equipped service shop on the premises with an extensive inventory of audio tubes,hardware,resistors / capacitors / transistors / switches / controls and a mind-boggling (!) library of schematics & technical reference materials compiled over the 35 years we've been toiling away in the biz!

Let's face it.Most of our competitors have actually cut back or quietly eliminated their "repair guy" to save money on their overhead & operating expenses.While this seems to be an ongoing trend,we are one of the few music shops to actually re-invest in technical training & equipment to stay on top of things.This allows us to serve your repair needs even better,leaving the other stores behind....

While todays more complex stuff isn't getting any easier to repair (let alone getting parts for some of these "things") our customers can feel secure WE take care of any problems with their gear.

When shopping around for an amp,guitar,etc,it would be worth your time (not to mention saving you some future service nightmares) to simply ask "the salesman" at some of the other music stores if you can SEE their service shop and talk with their tech department. If you encounter some strangeness to your request, or get fed some some lame excuse like-"it doesn't break down when it's new" (that one gets told alot), you might want to consider spending the extra bucks somewhere where you know it'll get repaired without a hassle. After all, who's going to repair your gear -Brad the salesman of the month or a non-existant technician? Sorry,but a 15year old part-time co-op student isn't "ready" to tackle fretwork on your prized GoldTop or McCarty,yet. We just call 'em like we see 'em.........

We are an independantly owned & operated repair facility and we don't have any favorite allegiances to any manufacturers. We can freely call 'em like we see 'em,warts & all,when it comes to amps.We presently perform non-warrantee repairs only,to tube (valve) & solid-state (transistorized) guitar & bass amps by Marshall, Traynor, Ampeg, Hiwatt, MusicMan, Fender and Laney,Mesa,SWR,Orange,THD and VOX.

Please call ahead BEFORE you bring your amp in,as our workload is constantly heavy due to requests for our custom shop setup work,guitar repairs,guitar overhauls and custom electronics work.
