The EHX is not that good, I much prefer the Mad Professor Underdrive, its not perfect but if you set your lead tone and volume on the amp then with the Underdrive dial everything back for your rhythm tone.I have an old 800 with no loop
I do not want to mod it
I had read an EHX Signal Pad was the way to go
Does anyone have any experience with this pedal?
Any other suggestions?
The master won't be maxed. I just need a volume boost for solosIf the master volume is maxed out, that's probably about all volume / head room you will get from it. Boosting it will only clip the preamp signal but will not significantly impact volume (assuming you're talking about a 2203/2204 type of JCM800). You could also try to bias the power tubes hotter
I'm trying to understand why anybody would have a 100 watt Marshall and need it to be LOUDER these days. That's a bit unusual.
Never had any problem getting the volume I need out of a Marshall.
Where you playing, Shea Stadium?
Given that the amp is only 50w, and If he's looking for a "significant" volume boost by merely stepping on a footswitch, i agree that this is one of the best options without modding the amp. I use the Unleash with my 50w 1987x for this, and it works great. Since he's got some headroom left (not running the amp wide-open), the amp could also be modded with an FX loop or 2nd master volume, but since he said he's not wanting to mod the amp, those options are out. For that particular amp, I would personally opt for adding a good zero-loss FX loop, which would solve the volume boost issue and also yield better results from time based FX pedals (Reverb, Delay...). It would also be less expensive than a re-amping device.I use a Bad Cat Unleash 2 with my 4010, it's a 2 channel re-amper that I use exactly for the reason you are looking for-giving me a volume boost for a solo. Works great on amps 50 watts and under. I don't believe it would support a 100w amp, though.
