Members RipVanWinkle7 Posted September 23, 2010 Members Share Posted September 23, 2010 Hey guys, I just recently bought a used Rivera Knucklehead KR55 top with the Headmaster (running that into a custom 2x12 with a v30 and a WGS Reaper 50) and am looking to experiment with the pre-amp tubes. It currently has the stock tubes (2 Sovtek 12AX7 LP's in V3 and V5, 3 Sovtek 12AX7 WA's in V1, V2, and V4, and 2 Sveltana EL34's). Here's a copy of the description of each pre-amp slot from the manual: V1 Input buffer and tone control driver for Channel 1, and also the first Preamp stage of Channel 2 and Channel 3 V2 Tone control follower for Channel 1 and an additional gain stage for Channel 2 and Channel 3. V3 Third gain stage for Channel 1 and final gain stage for Channel 2 V4 Final gain stage for Channel 3 and mixer for both channels V5 Phase inverter driver tube for the power amp section I play Worship music and Death Metal , so I am definitely taking advantage of the versatility of this amp. I'm boosting the front end with a TS9 (a Hardwire DL-8 Delay, Holy Grail Reverb, and Behringer EQ-700 EQ pedal when I play Worship music). I am pretty happy with the tone I am getting now, I am, however, looking for more definition/harmonics on Channel 3 and maybe a little less bass on Channel 1 and 3, I am having to use the FX loop trick in order to tame the power-amp for volume, this thing is ridiculously loud. What tubes would you recommemend? Link to comment Share on other sites More sharing options...
Members Dave L Posted September 23, 2010 Members Share Posted September 23, 2010 If you want definition, harmonics and less bass - try the Tung-Sol 12AX7 Link to comment Share on other sites More sharing options...
Members duncan Posted September 23, 2010 Members Share Posted September 23, 2010 You're not going to drastically change your tone with a tube swap. If you're looking to change the character of your amp, a pickup or speaker swap will do more. Link to comment Share on other sites More sharing options...
Members RipVanWinkle7 Posted September 23, 2010 Author Members Share Posted September 23, 2010 Would you recommend Tung-Sols in ALL of the pre-amp slots? And also, the WGS (Warehouse Guitar Speaker) Reaper 50 I have is a clone of of the Celestion G12H30 Anniversary, would I maybe want to purchase the WGS ET-65 (clone of the Celestion G12-65) or the WGS HM-75 (clone of the Celestion G12T-75) maybe to help? Or maybe swapping out the v30? Link to comment Share on other sites More sharing options...
