As stated on Philip Bynoe’s web page: “This is another pedalboard used on the Vai Tour. The Pedals are: Morley Distortion Wah Volume, Dunlop DC Brick Multi-Power supply, MXR Stereo Chorus, Tech 21 SansAmp Bass Driver DI, Morley ABY Selector/Combiner Switch, Boss TU-12 Tuner, Line 6 Relay G30 Wireless, and a Boss SYB-5 Bass Synthesizer.“more
When I was starting on the wee acoustic, this dinosaur kept me from sounding as terrible. While it cannot compare to the TU-2 that I now have, it was still a very useful tool. The only problem was I had no adapter, and I never had batteries, so that was annoying. But otherwise, it was a very reliable tuner.
The first tuner I ever bought. Purchased because it has a mic in addition to the line input (and I play horns in addition to electric guitar and bass). Worked extremely well, without fail, for many years. Anyway, it's ancient technology now and I couldn't even tell you where it is resting, but hopefully R.I.P.
