Mmmh, my amp is a JCM800 (with a master volume then) so do you think an attenuator would be of any use for me?
If you A/B (compare) a MV amp with a non master volume amp (let say the same amp got mod for a MV...), the tone difference is the MV amp will be fuzzier then the non MV fully dimed, you are missing the power stage distortion with the MV amp until you fully crank it then it is almost back to its NON MV tone but not fully (maybe 90-95%), so there is a lost somewhere but not by very much.....In the other hand if you use an attenuator with your non MV amp you will get all the power stages distortion all the time BUT those attenuator sounds like crap when you play at living room level (minus 16db like the hotplate can do), they are tone suckers at that level and your fuzziness with the MV amp might be better in most cases, if you use an attenuator but just to reduce a little, up to minus 4db or 8db then they are worth it but it is still damn loud....

So you get the best of both worlds here, the best advantage a MV amp will give you is tube life as you mostly play at low level, your tubes should last very long, if you fully crank your amp all the time and attenuate it your tubes are getting beat up real hard at the time and you will have to change them more often unless you are using NOS tubes but then again at the price those tubes sell for you don't want to kill them to fast....

I personnaly prefer a non MV amp plexi with a hotplate for attenuation a little.......

They are other mods you can add to your amp for more gain, like putting in cascade you pre amp section added to the MV then you'll have a monster gain/distortion amp, very easy mod to do and no drilling or anything, easy reversable.......it the one wire mod......For those who would like that mod added to there amp I could walk you through it very easy, get yourseft a 1meg resistor 1/2 watt is way ok, a foot of 20 gauge wire, a jack (with no wire attached to it), and a solder gun or even clips will work..........you will have to swap a few wires around and your done.... :wink:
