The Calico Effects Sunnmanor Preamp is a preamp pedal based on the classic Sunn Beta Bass amp's Single Channel. It is handmade one at a time, works with both guitar and bass, and offers a range from tone-shaping preamp to full bore distortion, according to Pedal of the Day's review1.
Controls
The pedal keeps things simple, with a small set of controls that cover gain staging and tone shaping1.
| Control | What it does |
|---|---|
| Level | Sets your output volume |
| Gain | Controls your distortion amount |
| EQ section | Three-band EQ with controls for the Highs, Mids and Lows |
The Gain control takes the pedal from a clean, tone-shaping preamp up to full bore distortion, so it can act as a foundation tone on a board or as a drive stage in front of an amp1.
Build and switching
The Sunnmanor has top-mounted jacks, which keeps the pedal's footprint tidy on a pedalboard, and the review describes the enclosure as built to last. Calico Effects pedals are true bypass, so the circuit drops out of the signal path when the pedal is off1.
"Simple controls make it easy to use, and the sounds you'll discover will blow you away..."
Where it sits among Calico's preamps
The Sunnmanor is one of several preamps in the Calico Effects range. The Calico Effects Pounce Preamp is a one-knob preamp booster based on the DOD 210 FET Preamp, while the Sunnmanor draws its voicing from the Sunn Beta Bass amp and adds a full three-band EQ1. For other preamp voicings and drive options, see overdrive pedals and distortion pedals.
