Radial Engineering Voco-loco

Have had this for a while. Struggled a little with it being noisy, but recently figured out you need to run it at a healthy gain level - if the gain is too low on the unit, noise seems to be added. Have it running clean now, and it sounds fantastic.

EQ is great - very responsive. Low and High only, which is limiting, but it's so dynamic you can deal with that. The FX loop, which is the primary reason for buying it, is wonderful - I'm running a distortion, POG nano, delay and TC HOF2 - and the mix of sounds and quality is brilliant - most of the time it's just the reverb, and it's a new world in terms of sound quality and control compared to anything else I've ever used.

Only thing that still bugs me and that I haven't managed to work out is the level difference from the FX being on and off. Unless you overload the input and receive levels, when it starts being uncontrollable in terms of the FX volume, it's far louder without the FX loop on. You can of course just turn all your FX pedals off, but it doesn't sounds as good as when the FX loop is off. Minor glitch that is work-around-able and other than that, a brilliant unit.

I was fed up with asking for certain effects on my vocals at sound check, only to find that the sound engineer would add more effects as they saw fit during the show and inhibiting the performance.
I played around with different vocal pedals but didn't really take to their features and felt they were overpriced with hardly any choice.
The Vocoloco allows you to use guitar pedals in a chain giving you a huge variety and choice. The pedal works as a preamp and stops the crackle and interference you'd usually get plugging straight into a guitar pedal as it changes the impedance.
The pedal is easy to use and allows you to be fully in control of the effects and is easy to turn on and off so you can sing without any effects and also a full mute button so you can quickly stop and sound going through the speakers should you have any problems with feedback etc.
I would definitely recommend this product to any singer wanting more control and more freedom with effects when on stage.

What a Wonderfull Tool!!
I use it all the time with my violin and Saxophone.

Violin: I use a Yamaha SV-250 electric violin and this preamp does a Wonderfull job!

Saxophone: Finally I can use my effects with my instrument! great sounds!!

pros: reliable, great sounding!!

cons: the "rare" power supply, can be fixed by using a cioks power supply or a Radial Tailbone Buffer.

The Radial Engineering Voco-Loco is a clever and well-built tool designed to integrate guitar pedals into a vocal or mic signal chain. It stands out thanks to its clean, high-quality mic preamp and properly engineered effects loop, allowing for reliable gain staging and a usable wet/dry blend -something many alternative setups struggle with.
In terms of sound, it performs very well: the preamp is clear and transparent, and the unit preserves vocal detail even when running through multiple pedals. The build quality is excellent, with a rugged chassis suited for live use. However, it’s not the most intuitive device -you’ll need to understand levels and pedal behavior to get the best results, and some effects can introduce noise if not dialed in carefully.
Overall, it’s a powerful and creative solution for performers who want to push beyond standard vocal processing. While it may feel complex for casual users, those willing to learn it will get a highly flexible and great-sounding setup.
