Thank you for viewing. This is the BJFe Model G. I purchased it from an overseas website several years ago. It's a rare 5-knob type, and I couldn't find any information about it on YouTube, etc. The knob controls are, in my opinion: V Volume D Gain T Tone (variable over a small range of high frequencies) P Presence (general TONE control) B Bass (low-frequency control) I believe so. The following is a quote from the official website: "The Model G is a drive pedal developed from the Honey Bee OD. Gibson amps, especially the old GA-40 and Falcon, are structurally similar to Supro amps, with clear similarities and important differences, and the Honey Bee OD and Model G have a similar relationship. The tone stack with three EQs allows you to create sounds with amp-like operability." It works without any problems, and there is no scratchiness. Please check the images for minor paint chips. Some of the internal sponge is damaged. Please also check that in the images. The only included accessory is the box; there is no instruction manual. This is a used item, so please purchase only if you understand this. We cannot accept returns or exchanges except for initial operational defects. Thank you.
