PAL800-V4 PLANTA - Fondo Negro_edited.jpg


PAL800-V4 GOLD Overdrive

This Hot Rod JCM800 in a box contains all the best of our 800 series in eight years of evolution with 3 different configurations, including an improved Mod #34 that has been the main tone of our guitar idol "SLASH". All this in a smaller and easy to setup format!


The PAL800-V4 GOLD Overdrive is a modified circuit of the JCM800 amp, replacing the vacuum tubes for very selected transistors carefully setup to perform the same way in each stage of pre-amplification, this 100% analog circuit is OP- Amp free and also clipping diodes free, all the pre-amplification and saturation are coming from the selected transistors the same way as the tubes in the JCM800 amp.

Thanks to the three-way toggle switch, we add 3 different configurations in this new version: 
JCM II Setting: In this setup we keep the original design from the PAL800 GOLD Overdrive that delivers a modern JCM800 tone.
Mod #07: In this setup we add our favorite configuration of the Gain Voicing switch from our PAL800-V3 Gold Overdrive into the circuit, allowing you to get more tone range & structure response in the gain section. 
Mod #34: The Mod #34 is better than ever! This famous modification that can be made in a 1959SLP or JCM800 amp is the main tone of our guitar idol "SLASH" and has been improved in this new version.

As in all our Marshall in a box style units, this pedal includes the "Master Tone" trimpot inside the main PCBoard to adjust the final tone of the pedal to your taste and gear.

Each pedal is carefully setup by hand for maximum performance and tested by the founders of PedaPalFx, therefore it is not a massive production pedal and there will be only a few per month available on the market, a true “Boutique Pedal”.
