Thank god you uploaded this. Too many guitar videos with these. Great video with tons of tone variation. Thank you very much

I love your videos. You should have 8,100 subs, not 81. Your SWR Grand Prix preamp with the graph is the best demo on RUclips. Your showing the graph is what makes you best.

Thanks for this, I have a clone someones built of this amp, and I wasn’t sure if the controls were supposed to be as interactive with each other as they are, or do things seemingly unrelated to their labelled purpose. This confirms that it’s functioning normally, it’s just a very freaky EQ on them!

Hurray..!! Exactly what I was lookin' for, extremly usefull video! Thanx :)

Great demo of the amp. What was the source of the high pitched oscillation @2:12-2:16? The audio interface? or was there another effects pedal in the loop?

[@jorge999903]

cool.

I have JCM 800 and 4x12 speakercab and my main problem is that when i go to 11 with vol this thing overheats and activates that overheating button from behind.

Very interesting. Notice the mid sweep is reversed.

good scratch on pot

[@pirhala]

What sounds like police sirens in the background??

Ridiculously obvious oscillation NOISE coupled with ridiculously scratchy pots. The ridiculous ground hum rounds out the trifecta.
