ianrendall Posted June 27, 2018 Share Posted June 27, 2018 (edited) Just got and fitted a lovely new Electro Harmonix valve from our friends at Watford Valves, as recommended by Derek as an early breakup valve. In short it sounds fantastic in my Trace. With the valve pre set to full, the gain at 9 and the low compression at half, it gives me that tiny bump of breakup at the edge of every plucked note. Been pursuing that tone for so many years and have finally got it. Edited June 27, 2018 by ianrendall 3 Quote Link to comment Share on other sites More sharing options...
Lozz196 Posted June 28, 2018 Share Posted June 28, 2018 Derek at WV certainly knows his stuff. I got a set of pre-amp valves for an Ampeg SVT-3PRO from them a few years back and it made a very nice difference to the amp, much livelier.

Pow_22 Posted June 28, 2018 Share Posted June 28, 2018 What valve did this replace? Im a sucker for valve rolling and have been messing with the 2 x 12AX7's in my Ashdown Spyder recently. Found a cheapo Chinese 12AX7 in V1 and a JJ in V2 sound best so far Quote Link to comment Share on other sites More sharing options...

If I was in the situation to change 3 preamp valves, I’d change all three. They’re cheap enough. Tonally, it could be interesting experiment to be mixing valves. Technically, I have no idea how a mismatch of valves would affect a bass amp. One for the experts. Quote Link to comment Share on other sites More sharing options...
