I open pretty much all gear I buy just to ... quality inspect it
the only one I didn't open up has been the Burl B2.... the great river mp2nv is pretty inside =D
I was gonna pimp my mpc - only got around to replacing floppy with a CF reader - no pics though. I bought a black skin for it and was gonna chrome it out.
completely modded a Urei 535 eq which I have pics of at home - installed XLR jacks on the back and replaced the opamps with sockets and put high end opamps in it. recapped with higher specd too. dropped the noise floor by almost 30db.
opened up the digitech studio 400 - all SMD - nothing I can do there :( could replace the opamps but have no experience with SMD circuits
bought a urei 562 that I was gonna mod - but then realized its not an EQ! no wonder they're so cheap lol. it only cuts, can't boost - but does have a HPF and LPF. was considering converting the circuit to be able to boost too, but haven't got around to it yet.
bought an 'already modded' symetrix comp - with upgraded opamps. sounds good enough for $110 that I bought another - will have to upgrade those myself though (need to match for stereo operation!) but they're already socketed, so its not really a challenge
sometimes I think playing with electronics is more fun than making music!
