Bass Poison Ivy (Bass Fuzz)


SKU: FGP-LR-BPI Categories: ,

The Bass Poison Ivy is an analogue bass guitar fuzz pedal with true bypass. This pedal has a germanium transistor fitted to give it a warm vintage fuzz tone. The blend knob allows you to go from a full wet signal to a full dry signal which allows you to dial in your required amount of oomph. This pedal has plenty in the tank and can give the bass guitar some subtle fuzz tones but still give you a nasty growl when you need it.

This pedal was featured in 2018’s Bass Magazine and this is what they said:

Meanwhile, the Poison Ivy fuzz pedal offers fuzz tones from the subtle to the extreme, and everything in between. How you wish to drench your tone with fuzz is determined by the Blend control, and the fuzz tone itself is impressive, whether you play with a pick, fingerstyle or slap. 8/10

    What intially sold me on this peddle was the blend control. We all know about bass distortions sucking away the bottom end, well not on this peddle.
    Unfortunately the demo above does not do this pedal any favours, it’s far more versatile. Whilst capable of nasty death metal/industrial distortions, I’ve used it a couple of ways: as an almost synth like effect; and to add some dirt on top to fill the sound during guitar breaks.
    So, Pro’s include the above, plus it looks particularly awesome (I have the blue graphic).
    Cons? The input/output are not labelled, which still confuses me even seven months later. There is not cradle for the battery, so it rattles around inside.
    Conclusion: well I love it. It’s versatile, sounds great and looks great, and Paul and the gang are awesome people to deal with.

      Hi Simon, thanks for the kind words and feedback. Glad you use it for what its made for and we’re currently looking at small identifying plaques to label the In/Out sockets so when they are made I will send you some. Best regards Team Flattley

    I’ll start by saying I am not really a fuzz user but having played through this pedal it really has got me thinking about using fuzz a lot more. The actual ‘fuzz’ tone is one of the best I’ve used. The build quality on these pedals is phenomenal, I would be willing to bet you would be hard pressed to find a pedal of this quality on the mass produced market. The art work and finish is flawless. The controls on the Ivy are super simple to use and be able to dial in the tone your looking for is a breeze.

    I love the input/output/power being on the top panel! I wish every pedal manufacturer did this!! It make’s wiring a pedal board so much easier and neater.

    Stunning pedals, can’t wait to try more.

    Excellent fuzz pedal for bass. Classic Germanium design, adjusted by the Attack knob, with a crucial wet/dry blend. LOTS of tone packed into these, with anything from very warm, woolly, vintage sound to a harsher, hifi, more gated fuzz. Works well with active and passive basses (have a play, it’s very responsive to what goes in) and stacks really well with other drive pedals; I use them to tame the high end in the more extreme settings and give the clean tone allowed through with the blend a grindy edge. Fan of Muse? You’ll like what this can do.

    I’m a gear head and have owned countless fuzz pedals and this is up there with the best of them. Better still, you’re supporting a small Uk builder!

    I commissioned a custom Poison Ivy with a gorgeous oil slick metallic finish, very high quality feel and looks fantastic on my otherwise very black/grey board.
