About Bill & Becky's Noisefree p'ups...there's tons o' talk around about the bridge plate metal - ferrous vs non-ferrous - regarding squealing and the prevention thereof. I'm wanting to put my 290TL (presently in another guitar with a Gotoh chromed brass bridge) in my avatar guitar with the Bigsby so I have to use the vintage steel plate that's been dremeled for string clearance...the Gotoh won't work. Squealing isn't the issue here, I'm just wondering if I can expect a tone change for the better or worse. Years ago I had a Glendale stainless plate with a Broadcaster pickup and it shifted the tone spectrum upwards...lost all the low end and had to keep the tone knob way down. Replacing the old steel plate made everything right again.
