Re: So, what Attenuator to get?
I bought a Hot Plate last year to use with my '77 Marshall JMP 2204.
I've used it for quite a few gigs and rehearsals and, whilst it's cool being able to get the master volume higher without blowing the windows out, I have not been totally bowled over by the attenuated tone. Most people will rightly tell you that bedroom level attenuated tone sucks, but even at gig level the JMP / Hot Plate combination has not been superly impressive. This may be down to the amp rather than the Hot Plate, but I've come to the conclusion I prefer the amp straight with the master kept low.
The Hot Plate is very well made with some cool features, but the big issue for me (apart from the above) is that the gig-level attenuation is in big steps - -4 dB, -8 dB, -12 dB. I find it really difficult to get the right level during a gig and when I want to adjust the level the steps are just too big. I'd like an attenuator with more precise control.
I suspect I'll be selling my Hot Plate at some point and either buying an attenuator with better control or making do without one.
