What should be my next pedal?
I like to play blues and classic rock. I've got a super reverb and just bought an Ibanez Tube Screamer
(which I really like btw).
What should be my next pedal? Chorus? Digital Reverb?
Again, I'm going for classic rock and blues.
If you get a boss RV-3 you'll get a digital day/reverb in one pedal, Plus it can be run stereo.
My personal favorite and a pedal effect one should not be without when playing certain blues and classic rock is the Wah Wah. I prefer the Vox to the Crybaby because it seems to have a greater tonal range, and is also more pronounced voicing. Check it out, http://www.voxamps.co.uk/voxframe.htm , it even looks badass.
My humble opinion.
Whatever pedal you choose, have fun with it.
