Been messin' with pre-amps quite a bit.
Stockers (including 3 of Mesa's condom tubes), JJs (RI), Tung-sol (RI), Telefunken (mid '60s),
3 Groove Tubes (Sovteks ?)and some gutless sounding Peavey re-lables.
Had an RFT in the V3 slot with the 2 T-Funks, sounded good for about 2 minutes
'til it went...
