Well, with me going out today with the plan of buying a 100 watt head, I've been convinced by all of you to get a power soak as well. Unfortunately, my weaksauce status as a retail worker means that my options are limited, but promising. Budget is very much a concern, as I'm not exactly rich right now.
I've found three options I can feasibly get, since a rockcrusher is out of my price range by a lot. The first is the Jet City Jettenuator, which doesn't seem to be getting the best reviews as far as tone suck goes, but it's quite cheap new.
The second is the old Rockman power soak, which sounds decent in the videos I have found, but many people seem to find them to be less than ideal. It has the advantage of being incredibly cheap, however, and you can pick it up for around 100-125 off ebay any day, since there are so many listed.
The final option is trying to get a hot plate cheap. They're around double the price of the other two, even when it's a deal, so I'm unsure whether it is worth it. Of course, if they sound transparent and work great, then that would be optimal.
Opinions very much welcome. I'd love to hear from anyone with experience with these models.
EDIT: And to clarify, I wouldn't be cranking the hell out of the amp, I'd just be looking for enough attenuation where I could let the poweramp open up but be able to stay on speaking terms with my family.
Don't get an attenuator
Just turn it down. No, you won't get that cranked sound at low volumes, but you STILL won't get that sound with an attenuator. All they do is help you burn through your power tubes faster.
