Hey all. My first post. Been a huge Bonamassa fan for a few years now and live in his hometown area. I used to try and use pedals for all my saturated singing tones and it never sounded like a great tube amp cranking. Joe's right about a power soak, the THD HotPlate is my favorite, and works well with just about every amp I've ever tried where's I need one. I've used them on 100 Marshall's and 50 watt Marshall like amps with great success. I live in the city limits, houses upon houses and can't play real loud ever. Also my wife gets sick of listening. LOL!
Right now I use a Ceriatone Expression (Trainwreck Express clone) amp. 50 watter 2 x KT77 powered and I run the volume on it at half way which is super loud without a power soak.
Here's a clip I did last night of it using a '58 Les Paul Historic model. It was maybe as loud as a TV turning a good movie. I could hear my guitar strings over it. All the distortion is natural amp distortion except at the 3:01 mark I step on a Klon for a bit for more sustain and compression....and borrow a Joe lick. Excuse my sloppy playing, but it gives you an idea if how cool a power soak can be for you.
