The Roland RE-201 Space Echo contains a tape drive - therefore Tape Echo - with three tape heads and a spring reverb. A mode switch activates the three tape heads and / or the spring reverb in fixed combinations. Mode 1 - 4 only echo, mode 5 - 11 echo + reverb and mode 12 only reverb. The reverb and echo volumes of the Roland RE-201 Space Echo can be adjusted separatly. With an intensity control you can adjust the feedback and herewith the number of echo repeats.
2001 I bought the Boss VF-1 in order to complement my Line 6 Pod Pro. But, contrary to the dust collecting Line 6 Pod Pro my Boss VF-1 is still in use. Not as a guitar processor but because of the special effect algorithms. I want to introduce some of it's effects because I saw a Boss VF-1 on ebay germany sold for 150 EUR. 2001 I paid approx. 450 EUR and for 150 EUR it's a bargain.
The Boss VF-1 consists of so called algorithms which provide the different effects.
