Recently I had my 2061x modded with the "Swank Motee" cascade mod.
It has turned my little mini-Plexi into a fire-breathing monster, I'm extremely pleased with it.
I push the front end even harder with a Blackstar HT-Boost pedal on maximum boost, and for the first time I am very happy with the sound from the 2061x - think Blackmore's "Made In Japan" tone crossed with Hendrix's "Band Of Gypsys" tone (I'm mainly a Strat player).
It's pure early Sabbath with an SG and the boost pedal.
Has anyone else tried modding a 2061x?
