Reminds me of the time we played a show, and it was early early days of the band and I didn't have an amp. So I took my Fulltone OCD along and was just gonna play through the house amp, which was a tiny Fender combo thing. It was shit.
The headline band (bunch of nobodies really) wouldn't let me borrow their amp, because he didn't want me to mess up his controls.
Mate... you were playing a fucking Marshall Mode Four... it was gonna sound like dogshit whatever you set the knobs to!!
