Well I'm extremely disappointed with Bass Northwest. After getting a great quote on the SVP-Pro preamp, I ordered it and my credit card was charged November 21st. The dude on the phone said that they'd order it from Ampeg right away and ship it out the next week to me. Well 2 weeks go by and I start calling this week, and they don't know whats going on so they got ahold of their Ampeg rep. Apparently the SVP-Pro is not going to be made anymore? ***! They said they had a SVP-CL in stock that I could have instead.... is there a huge difference between the two?
