Completely rebuilding a Sunn 2000S. #baltimore #bigcrunch #amprepair #tubeamp #sunnamps #vintageamps @mercurymagnetics
It’s amazing that I still see Fender amps from the 60s and early 70s with the original filter capacitors. These are obviously very bad. #bigcrunch #baltimore #amprepair #tubeamp #vintagefender #fender
RED! #bigcrunch #baltimore #amprepair #tubeamp #matamp
A real deal 1961 Fender Champ! #bigcrunch #baltimore #amprepair #fender #vintageamps #tubeamp
A fantastic 1974 Princeton. One owner! Just had an overhaul and sounds amazing. #bigcrunch #baltimore #amprepair #tubeamp #vintageamps #fender
Finally finished a new batch of Boost pedals in mini enclosures! Up to +24 dB clean boost. #bigcrunch #baltimore #efxpedals #diypedals #guitarpedals
Not only do we play the amps, but we monitor and measure the output power of every amp before it leaves the shop. #bigcrunch #baltimore #tubeamp #amprepair
Amps made after 2000 that need cap jobs are making me feel old! #bigcrunch #baltimore #amprepair #capjob #tubeamp
A Blue Voodoo no more! Look at this custom designed build for a client - 30 watt, all tube, two channel, four gain voicing options, reverb, built in output power attention. #bigcrunch #baltimore #tubeamp #tubegain #guitaramp #mercurymagnetics
Custom build with Mojotone Dijon coupling capacitors. @mojotone #bigcrunch #baltimore #tubeamp #capacitor
