I’m a huge fan of Bleak District Phil’s unique sensibilities in circuit design. And I’ve long since acknowledged him as a master at knob selections - the 5 knobs on this one are just perfectly balanced!
And the overdrive itself is pretty unique. Based at its core on a high quality RC4558 OpAmp - but with a hybrid mix of both asymmetrical silicon diodes in the OpAmp ’soft’ position and germanium diodes in a hard clipping position. Furthermore we have JFET buffers for the Drive and Clean sides of the circuit.
Phil described the circuit to me rather amusingly - as a sort of mashup of a Tube Screamer and DOD250 - with some extra bits!
It does have a wonderful organic harmonic richness to its output though - with the JFET Buffers and hybrid clipping really helping mould that distinctive breakup.
Controls - Volume, Gain (+40dB), Notched 8-way Low Frequency Filter, JFET Buffered unfiltered Clean Blend with boost, Top-End Smoothing.
The inclusion of Clean Blend makes it an excellent choice for Bass players too. It’s really a 2-Band EQ as such - where the overall topology is made even more special courtesy of the perfect selection and arrangement of knobs.
I did comment at the Brighton Show that the pedal had an air of EVH Stripes about it - but this of course has nothing to do with said great axeman - just a really cool way to illustrate the 8-way notch filter.
The Terra is a really cool, actually a rather warm organic overdrive with distinctive character and a lot of versatility. Ticket price of £145 makes it very reasonable - I will certainly be looking to pick one of these up in the not too distant future. And I still need to get my hands on a Sun?No at some stage - all in good time as they say. You can order a Terra right now from the Bleak District Webstore.
