snansamp bass driver does the modern Geddy if that is the sound you are looking for. And by that I mean the 2000 to the present. Alot of guys dont dig that tone of his. I had the sanamp bass driver for years, its good, but not for the classic geddy.
The VT pedal will get you there. After all, Geddys live rig back in the seventies, included a direct signal to the house, and you will notice in pics, an Ampeg V4 Mic'd up(probably his overdriven tone).
on this link, im playing the VT pedal on the various pages.check it out.
Am I in the Geddy Lee ballpark with this sound?
I also have the Vintage Microtubes pedal. Its a cool pedal, but I think the VT does the early Geddy Lee better.
If you are looking for the geddy sound, it stops with the ged2112 preamp by tech 21.
You won’t get any closer than that.
