For sale is a fantastic boutique bass preamp and overdrive pedal from the Australian builder Mozztronics — the BP-7 CMOS Bass Preamp. Handcrafted with incredible attention to detail, this pedal is a secret weapon for bassists looking for massive tonal versatility and professional features. 

The Sound & Features:

 Massive Tonal Range: Thanks to its internal jumpers and dual-path design, you can dial in anything from warm, tubey Motown-style tones to aggressive, mid-scooped Darkglass-like overdrive.  

 Dry/Wet Blend System: Instead of a standard volume/blend setup, the BP-7 splits the input into two paths. One path keeps your clean dry signal punchy and intact, while the other runs through multiple clipping stages into the wet volume control. This lets you retain a massive low-end foundation while adding as much grit on top as you want.  

 Amp-Style EQ: Features Bass, Mid, and Treble controls. Note: The 3-band EQ works in an amp-style cut configuration (cuts frequencies rather than boosting them), giving you incredibly musical and transparent tone-shaping.  

 Contour & Internal Jumpers: Includes a toggle switch and internal jumpers to tweak the filter, gain structure (Hi/Lo), and EQ routing for ultimate customisation.  

 Built-in DI: Features an XLR output with a ground-lift switch for direct connection to mixing consoles or audio interfaces, with the DI signal controlled by the footswitch.  

Specs:

 Power: Standard 9V DC (Boss-style center-negative, 2.1mm). Important: Do not use 12V or 18V supplies!  

 Build: Rugged enclosure, side/top-mounted jacks, handcrafted in Australia.
