A firm natural overdrive with a pleasant silky sustain. An easy to handle overdrive with great sustain without any unnatural compression. It keeps the characteristics of the tones that the guitars naturally produce. The Jan Ray reproduces that great sustaining punchy clear tones of the blackface Fender amps from the 60's. The tone is crispy yet the low is warm and mellow.
And it only costs £300 here in the UK for a blatant rip off! Bargain! And so I strongly suggest anyone considering buying one gets themselves a Timmy instead or makes it themself.

I like the compressed setting on the Timmy and so have added an updated layout which includes an additional switch to choose between compressed and uncompressed symmetrical clipping.
