An high end, 4U rack, dual mono, 2bus and Mastering Equalizer, a bandaxall section with an additional mid band, HPF and LPF, switchable custom transformers (also with eq bypassed), all stepped controls.

Designed in collaboration with MixbusTV, only 10 units built in total for the first limited batch of production. Each unit was numbered.

Now we are ready for the next “standard” hand made production, custom released on order.

Price 2800 Euro
