Master your tone with the MXR Six Band EQ—your secret weapon for dialling in the perfect sound. Six sliders give you ±18dB of boost or cut across all the frequencies that matter for guitar, so you can dial in anything from fat, scooped rhythms to warm, natural acoustic tones. Need to tame feedback on stage? Done. Want to sculpt a massive lead boost in your amp's effects loop? Easy. True hardwire bypass keeps things transparent when you're not tweaking. Power it with a 9V battery or AC adaptor (ECB003) and get creative.
