‘Lurn’ me about Range Master treble boosters!!

[Len058]

I built 'The Range' it has a nice switch to change the frequency. I don't like the Rangemaster setting, but do like the milder settings.

The range master won’t work as well with a fender amp or a Marshall as it will with a Vox.

They're great with Tweed.
