When they go low, go even lower with the M288. Additionally, M288’s other two knobs allow players to add more midrange or low end. Its dry knob allows one to mix affected and original signals while adding up to 15dB to the midrange. Its dry knob allows one to mix affected and original signals while adding up. MXR M288 Bass Octave Deluxe is a two-voice octave pedal with true bypass switching. Using the same sounding filter is a guess as without sound samples we still don't know if the Octave sound of the "MXR Bass Octave" is the same as the Girth sound on the Bass Octave Deluxe. MXR M288 Bass Octave Deluxe is a two-voice octave pedal with true bypass switching. However, it is possible to make the MXR Bass Octave Deluxe with the 3圆8k resistors sound the same as the filter in this circuit. If you look at the schematic for the "other" "MXR Bass Octave" (I'm not actually sure what MXR pedal that is yet), you can see the same 330k as the Girth channel. So one part of the waveform gets stretched and clipped, which changes the character of the tone. That means when the JFET (Q10) is off the gain is about 1 but when the JFET is on the gain is about 7. If you look at R51 (330k) the V0.1 schematic it's a high value. The Bass Octave Deluxe does a bit more to deliberately change the tone on the Girth. You can hear the difference between the different methods. synth.pdf, due to absence of diode before U5, the wave won’t have the same DC offset. It looks like both girth and growl have to differences: different low pass filters and probably a different wave shape.Īs I red here.
