HThese were a highly regarded overdrive, although they weren't made for a long time. There's some clever engineering involved to get the valve to perform properly at a lower voltage; it'll run for ages on batteries. The tone is very much Vox flavoured; there's a heap of punchy mids and chiming top end on offer... chipper!
