Stereo Amp Setups.
I've gone almost totally stereo. I blame part of it on my 12 string Ricky that just sounds like a wall of sound when played through two amps. Throw in the "Not Allowed to Use Drugs" part of my contract with my employer and the spacey qualities of a stereo amp setup becomes just that more important.
A pair of identical amps are the most important part of this rig. The pair of amps having ground switches is the next major part. After that it comes down to power isolation to reduce / omit ground noise and pedal board effects designed specifically for stereo. There aren't that many out there but, with a lot of searching, you can find at least one excellent example of every effect other than "gain" pedals. I consider gain pedals to be almost like a part of the mono instrument going in so this doesn't matter to me. There are excellent stereo Delay, Reverb, Chorus, Echo, Phaser and Flanger pedals out there. It's been over thirty years since I've had a joint but this setup brings me damn close.
Anyone else getting into / exploring the possibilities of a stereo amp rig.
