[QUOTE="Ricey, post: 154580, member: 1820"] What would be the best replacement preamp tube(s); e.g., 12AY7, to increase headroom in a stock Randall Tweed Module. I can get a great sparkly clean tone with the gain below 10 o'clock, but it starts breaking up quite a bit after that with humbuckers. I am using that module in channel 1 in my RM100 combo as my primary clean channel, so I would really like some additional headroom. Can tubes be mixed and matched in the modules; e.g., mix a 12AY7 with a 12AX7 or do they both need to be the same? GC has lower gain 12AT7s, not 12AY7s, but I notice 12AT7s seem to be mostly be used as phase inverter tubes, so I did not buy one. [/QUOTE]
