Re: suggest New High Gain Amp
On the high gain channel, the Speed Twin is in Soldano/Bogner territory, the mid gain is JCM800, the clean channel is like a Fender preamp through a Marshall power amp (basically what it is). It's a great amp, I just saw one go for less than $500 on ebay, I almost cried

I bought mine for a little under $800, and it's worth every penny, they were around $2K new. These are a stupid deal for what they are going for on the used market. They will also run EL34s or 6L6s, I'm running EH 6CA7s in mine now and really like them.
I had a HR50+ once too, another one of my favorite amps, more basic with less bells and whistles than the Trace, but had killer tone, I haven't played a SLO, probably shouldn't... The high gains are similar, the Soldano may be a little more organic sounding, but I've never had a chance to try them side by side.
Hope that helps,
Roger
