Hey all, I have a 1989 2554 that I rehoused into a 2x10 built by Sourmash, I didn't like the boxy tone of the 1x12" and it was heavy as could be, so I had Bob build me a 2x10 out of pine, and it's definitely a winner! I'm running it with 2 JensenMod50 10" speakers, each at 8ohm wired so they're producing a 16ohm load, with the amp adjusted to match. I've gigged with it once since I rehoused it, and had gigged with it prior in the 1x12, and both times I was surprised that I needed to bring the master up to around 7 to get through the mix. I run it on the Lead Channel, the Input Gain at 7, Lead Master at 7, and then run the tone stack as Treble 4, Middle 6 Bass 8, and presence at 2. I like the tone, and it cuts through great at the higher MV setting. Messing around with the settings is a ton of fun - if I run the master volume wide open, and use the Lead Master as my "volume" and run the input gain at 7, it sounds glorious...but I'm not used to running things wide open, and wanted to gather some input from those that have used these amps in the past. I know the preamp and power amp tubes are 6 months old (JJ pre and Winged C power), it's dead quiet, and sounds great - but just wanted to see if having to bring the master up that high (and use the lead master to control volume)was common practice. TIA!
