Can't speak for the Ampegs, but I've never found the LB-30 / CTM-30 lacking in midrange. I did find the Mid-Shift switch particularly useful for shunting the centre frequency into the a "sweet spot." Also, I think I'm right in saying that the EQ is similar to an old-fashioned FVM-style tone stack (someone please correct me if I'm wrong), so by backing off the bass control, I can give the mids and treble more room to "breathe" - at home I'd typically have the bass knob around 8 or 9 o'clock, and the mids and treble at noon. (The high shelf introduced by the Bright switch is also quite useful for definition if you need to keep the volume down!) Quote Link to comment Share on other sites More sharing options...

Apparently British valve amps that use British valves produce a more warm 'scooped;' tone and American Valves are supposed to be 'flatter' with more midrange. It would be interesting to swap out the EL84s for say, a 6BQ5 or other American variant and assess the difference. (of course you would have to talk to an amp tech to avoid unwanted fires.

Sir Spence Posted January 30, 2019 Share Posted January 30, 2019 6BQ5 is just the American name for the EL84 - same thang! 6P14P if you speak Russian 🙂 Quote Link to comment Share on other sites More sharing options...
