The AJH Mini Mod VCF, Transistor Ladder Filter is a faithful replica of a Moog transistor ladder known for changing the electronic music landscape.
There is a three channel input mixer and a nice large filter cutoff control, along with “1/3” and “2/3” CV inputs to emulate the action of the original VCF keyboard switches, apply 1v/oct to either of these inputs and the VCF keyboard tracking will be the same as the original with Keyboard 1 (1/3) or 2 (2/3) engaged, or use the 1v/oct input to emulate both switches selected. There is a variable Exponential CV input which is about 30% more sensitive than the 1v/oct input, this allows some nice over modulation effects.
AJH have added Voltage Controlled Resonance (Emphasis) in addition to manual Emphasis control. This uses a vactrol as the control element. The fast vactrol used allows modulation speeds up into the audio range. The filter will of course self resonate and act as a sine wave oscillator too.
There is also an overdrive facility which can be selected with an onboard jumper. This allows the input to the filter core to be substantially overdriven, great for adding a bit of extra dirt to the sound.

Had the urge ordering AJH Synth MiniMod VCF black and Musicstore was the only online shop whit this in stock. I know this brand so was happy that the module landed that fast so I could use it at the next performance. AJH Synth is a brand that is one of the top brands in the eurorack market; the AJH Synth MiniMod VCF black is one of the modules to incorporate the "Mini Moog" into Eurorack... Sounds great & the built quality is superb. The filter has an own unique sound comparing it with other filters out there.
