Three new Feedback CMS-Lab collaboration modules: Lazer Phazer stereo phaser and VCZIII VCF and JP8 VCF, VCS3, and Jupiter-8 filter clones
In February, I first reported on the collaboration between Feedback Modules and CMS Lab. At that time, they released the VCZIII modules, oscillator clones/replicas of the legendary EMS VCS3 Synthesizer. Optionally, with the EMS-style, Bourns multiturn fine-tune potentiometer.
The VCZIII series has now been expanded with the VCS3 VCF. A new Jupiter-8 filter replica and an exciting stereo phaser called Lazer Phazer from Feedback, and CMS Lab are also brand-new releases.
Let’s start with the new filters.
Feedback CMS Lab VCZIII
VCZIII VCF is a recreation of the filter circuit of the legendary British EMS VCS3 pin matrix Synthesizer, which was released in 1969. It has various enhancements and adaptations to the Eurorack needs of the 21st century.
On the circuit side, the modules use various well-selected components:
- AS394 ultra well-matched monolithic NPN transistor pair
- selected and matched BC550 and BC560 transistor pairs
- WIMA capacitors
- selected 2N3819 FET transistor
The Feedback CMS-Lab VCZIII VCF is a 12HP module with classic cutoff and resonance controls. Both are CV-controllable and offer a dedicated attenuator. There is also a two-channel mixer with dedicated levelers.
Feedback CMS-Lab JP8 VCF
Yes, they look pretty much the same but are different filters. The JP8 VCF is a modern recreation of the legendary Roland Jupiter 8 Synthesizer filter. Like the VCZIII VCF, it uses well-selected components to archive the sound of it:
- S3109D and AS662A, ALFA RPAR modern identical to the original IC clones
- WIMA polypropylene capacitors
- selected 2SK30ATM-GR N-channel J-Fet transistor
The JP8 VCF is a 12HP analog filter with a selectable 2-pole (12dB/oct) or 4-pole (24dB/oct) lowpass topology plus a high-pass filter. Besides a 2-channel mixer with dedicated knobs, the module has classic filter controls, including independent cutoff for LP and HP as well as high-pass.
It also has two CV inputs and independent outputs for 2-pole, 4-pole.
Feedback CMS-Lab Lazer Phazer
Besides the new filters, Feedback CMS-Lab also released the Lazer Phazer, a flexible 18HP stereo phaser for Eurorack. It can work as two indepdenent mono phasers, mono bi-phaser, or as a stereo phaser. Alternatively, you can turn it in a 16-stage phaser in series mode.
According to Feedback and CMS-Lab, the Lazer Phazer uses 16x2SK30A fet transistors matched and selected from new old stock, so the retro sound it’s totally there.
Nice, the LFOs (slow/fast) that are part of the phaser circuit can work indepently, or linked in inverted mode for lovely stereo phase manglings. On top, you can modulate the feedback with the internal LFOs, external CVs or both of them in the same time.
On the interface, you have two identical sides, each with a big resonance knob, switch for slow or fast ratios, and potentiometers for rate, intensity, level, and CV in. Further, you have on each side, a mono input, output and a CV input.
First Impression
At first glance, three beautiful, exciting modules from Feedback and CMS-Lab. The dual phaser/stereo phaser in particular looks very tempting. It’s a shame that there aren’t any sound demos yet. I would have loved to hear them.
The new Feedback modules are available now: VCZIII VCF for 238€, JP8 VCF for 238€, and Lazer Phazer for 297,50€. All prices with VAT.
