Some house show hosts will have to take a percentage of the door cut to cover their costs, but in most situations, it’s the performing artist who ends up with the lion’s share. Playing a big ol’ fancy venue might be an impressive thing for a burgeoning band to brag about, but with all the staff and overhead costs, the bands won’t earn any money unless they’re able to fill it. At a house show, you’re not expected to bring in hundreds — you can even make the gig free to attract more people and ask for donations.
The Space Echo is a tape delay pedal with a spring reverb plate built into it. Roland had made other tape delay machines before the RE-201, but adding the reverb plate colored the sound in a unique way. The way it combined both effects was fairly unique at the time, and artistically done, but now that’s fairly common across different guitar pedals, plugins, and outboard delay boxes.
