Would appreciate some advice. I bought a circa 2000 Twin Reverb RI earlier this week but the guy had lost the foot switch when I showed up - I paid him a little bit less, and he told me he would bring by a foot switch for me as we live very close and I'd shore up the rest with him. He's a cool guy and was true to his word, but he brought me a Boss FS-5L brand new in the box when I was expecting the RI Twin Pedal. I've never had a RI Twin so I'm only familiar with the old RCA foot switches. Plugging the Boss pedal in does allow me to turn on the Trem, but just the fact that it's plugged in (whether the trem is on or not) turns off the reverb. Advice? If it was the other way and the reverb was always on, that would be fine - I swim in reverb. Thank you.
