Rangemaster Cutoff Frequency Modifications

The Rangemaster Treble Booster can be modified for wider boost range.
Here are the frequency calculations and some suggested capacitance.

By adding a couple of capacitors and a 3-way switch to your Rangemaster,
you can have settings for "stock" tone, a "full range", and a "super full-range".



Best Regards,

And the Beano. Don't know about specs, but there's a switch. I always leave it to stock specs anyway.

There are quite a few Rangemaster clones with this type of modification. If you have a treble booster with the original Rangemaster circuit, though, you can use this data to modify the treble frequency cutoff. The 3-way switch gives three options, including "stock".

I'm going to have to look at the values on my Beano Boost. I got this thing thinking it would literally be a treble boost, but mine behaves more like an overdrive pedal, in all three switch positions.

Normally that would disappoint me, but the fact that it absolutely nails the tone on the Paranoid album makes up for that.
