Want a very smooth rich tone with less grit? This is the Gold Pin Option for the Mesa Roadster and Trem-O-Verb amps. The preamp section uses six Gold Pin JJ ECC83S's with one balanced for the phase inverter in V6. The default power tubes are the JJ Electronic 6L6GC’s. With the Customize option you can configure this kit to use the JJ 6V6S's, 5881's, KT66's, 6550's, KT88's, EL34’s, EL34II's, E34L's, KT77’s or Big Bottle 6CA7’s. And if that isn't enough we also have Integrated Quad options! If your amp is the combo version then please let us know in the comments section and we will ship your kit with the special Double Mica 6L6GC’s which will greatly reduce any tube rattle.
