Unify Pedals and Eurorack
UniFX is a compact and flexible effects interface that interconnects guitar pedals and electronic instruments with eurorack synthesizers. The module re-scales audio levels, offers voltage-control over the dry/wet mix, and uniquely allows for the primary and effects signals to swap sources.
Effects Loop
UniFX makes it easy to process eurorack audio signals with pedals, or to process external instruments with eurorack modules. Essentially, it is a level-scaling effects loop. The module has two pairs of mono IN and OUT jacks for signals—3.5 mm at eurorack-level and 1/4-inch at pedal-level. The slide switch labeled PEDALS-EUROFX swaps which jacks are used as the primary input/output and which are the effects send/return.
To process eurorack audio signals with guitar pedals or outboard gear, use PEDALS mode. The eurorack source signal is patched thru the 3.5 mm IN and OUT jacks, while any pedals are connected to the 1/4-inch IN and OUT jacks.
To process line-level instruments or guitar with eurorack modules, use EUROFX mode. The line source signal is patched thru the 1/4-inch IN and OUT jacks, while any effect/filter/etc modules are connected to the 3.5 mm IN and OUT jacks.
Audio level scaling is approximately ± 12 dB, appropriate for most pedals.
Mix Control
The FX MIX parameter is a variable crossfader controlling the dry/wet balance of the input and effects return signals. The amount of effects mix is indicated by the WHITE LED. With the knob turned all the way down, only the input signal is heard from the OUT jack and the LED is off. Alternately, with the knob turned all the way up, only the effects return signal is heard and the LED is fully illuminated. The center position produces a 50/50 mix.
This parameter may also be automated using the CV input labeled MIX, wherein the knob position is used to bias the incoming control voltage. The full range of the parameter is 10 Vpp, so a typical LFO of ± 5 V will fully sweep the FX MIX up and down if the knob is in the center position.
VCA & Feedback Effects
Because the circuit is VCA-based and DC-coupled, UniFX may also be used like a typical VCA module for both audio and control voltages. The only difference is that the control input works in reverse—as the voltage is increased, the signal is reduced. Simply run the primary signal through the 3.5mm IN and OUT jacks, connect nothing to the 1/4-inch jacks, and select PEDALS mode using the switch. Turn the FX MIX all the way up to have no dry signal, and apply a negative going control voltage to the MIX CV input.
Additionally, due to UniFX’s switching effects loop topology, feedback effects can be easily achieved. Just slide the switch into the “wrong” mode, and turn the FX MIX parameter down to increase the amount of the effects return being fed back into the effects send. The MIX CV input can also be used for experimental voltage-controlled feedback effects.
Patch Tips
FEEDBACK MODULATION – Patch a signal through the 3.5 mm IN and OUT, and a guitar pedal to the 1/4-inch jacks. Put the switch into EUROFX mode. Patch a CV with negative going voltages into the MIX CV input, and bias the knob so that effect feedback comes in and out to taste. This patch is especially interesting using reverb effects.

How much is my shipping?
Shipping is automatically calculated before you submit your payment information. Simply add items to your cart and proceed to the checkout page, where you'll be offered shipping options and their prices. In the UK it's normally around £4 for order values under £150, and free above that. Shipping to mainland EU is typically between £7 and £20, depending on the shipping method and the size and weight of the order.
Do you ship to my country?
Almost certainly - the site will give you an estimate of shipping costs if you add an item to the cart and then enter your country and postcode. If you have specific requirements (such as if you prefer UPS over FedEx, for example) then let us know in advance and we'll try to work something out for you.
Shipping methods
We use a combination of Parcelforce, DPD, Royal Mail and UPS for the UK, and for international orders it's either Royal Mail, UPS, DHL or FedEx depending on where you are in the world. If you have a particular preference then try to let us know BEFORE you order so we can look into it for you. Please note that there may occasionally be additional shipping charges if you live in a remote area, depending on what surcharges are applied by the shipper. We'll get in touch to discuss this with you in such cases.
Dispatch times
For UK orders, we normally dispatch the same working day if we get the order before 15:00. If you have a really urgent situation then of course drop us an email before ordering and we'll always do our absolute best to accommodate you.
For international orders, we normally dispatch the same day if we get the order before 13:00 but again, occasionally it might be the next day before we can send it out, and sometimes FedEx or UPS may come a little earlier than scheduled which would also push an order into the next day.
Shipping times
Since April 2020 the couriers we use have suspended guarantees for shipping times, so even though we're paying them for priority services - 24-48 hours for most of the world - in practice it's often an extra day on top and sometimes it can be longer.
There is absolutely nothing we can do about this unfortunately. If you are outside the UK and it's a life-or-death situation where you absolutely MUST have that passive mult for the next day then... it may be better to find a local supplier.
Saturday shipping
If you're in the UK and you order before 15:00 on a Friday then we can send something for a Saturday delivery (NB: this applies to UK mainland addresses only). The success rate with DPD is about 95% so it's worth a punt most of the time. Please note that if you select Saturday shipping on an order placed earlier in the week, we'll wait until Friday to ship it.
Pre-orders
If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.
If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch if you have questions.
