A sweet and sticky tube amp style overdrive that really reacts to your pick attack.

Add rich harmonic overtones to your riffs and give your sound a sting in the tail!

The CP503 features the following control knobs. The Volume Knob controls the overall signal volume. The Drive Knob controls the amount of gain added to your signal – from tube-like sag to gritty overdrive The Focus Knob adjusts the overall EQ brightness and the level of dynamic pick attack, allowing you to dial in the sweet spot on single coils, humbuckers or P90’s.

Super OD Pedal

By: on 8 October 2023
This Queen Bee OD pedal packs a lot of punch for its price. In my opinion an excellent first stage, low gain OD, that gives you that classic tube amp break up sound. Love it for rhythm especially.

Caline Queen Bee CP503 Overdrive

Bought in conjunction with Caline CP516 Orange Crush overdrive, at this price I didn't see any need to decide between the two. It has a fairly bright, articulated sound with very little fizz. I find it great on its own, when I am after strong, clear grit, or stacked after a Caline CP12 Pure Sky to push for more distortion. Haven't contemplated taking it off the board, which I think sums up what I think of it. Excellent price and service from Artist Guitars, unchanged over the years I have been purchasing from them.

Caline CP503 Queen Bee Overdrive Guitar Effect Ped

Great sounding overdrive pedal. Great price. Actually sounds good playing a guitar (strat style) through a Fender Rumble bass amp :-) Also good pushing the front end of an old silverface twin reverb (master vol early 70's model, I think my ears are still bleeding) and even the front end of a Boss Katana 100. Great customer service from Artist Guitars.

I like this pedal alot I like the way the focus dial functions and when coupled with my distorion pedal, how it changes the tones. Artist Guitars, you've done it again, another great pedal at a fantastic price
