    Hi guys.
    I just opened the amp to see what tubes were inside (had it for a couple months) and noticed three RFTs, ECC83 in V1 and V3 and a ECC81 in V2.

    I have never seen a ECC81 used in V2. Anyone doing it?
    I have used it as PI in high gain amps and liked the effect.
    Btw, the amp sounds gorgeous boosted. One of the best sounds I've ever had.

    The ecc81 is a medium gain tube by putting it in v2 you get to overdrive the tube a little more .

    You mean lower gain tubes give more overdrive?
