Blackstar Ht Dual Pedal: Schematic

The Blackstar HT-Dual is a modern classic in the world of tube-driven distortion. Unlike "starved plate" designs that run tubes at low voltages for show, the HT-Dual uses a high-voltage internal power supply to get genuine valve compression and harmonic richness.

Troubleshooting the switching power supply requires an oscilloscope and advanced knowledge of high-frequency electronics. If you'd like to dive deeper, let me know: Are you trying to repair a broken unit?

Understanding the schematic is key to maintaining, modding, or cloning this beast of a pedal. ⚡ The Core Architecture Blackstar Ht Dual Pedal Schematic

A dedicated filtering circuit at the end of the chain that rolls off high frequencies to mimic a 4x12 cabinet.

A complex arrangement of FET switches and logic gates that toggle between the "Clean/Crunch" channel and the high-gain "Lead" channel. If you'd like to dive deeper, let me

Blackstar’s proprietary "Infinite Shape Feature." On the schematic, this looks like a specialized tone stack that shifts the center frequency and response between "American" (tighter, scooped) and "British" (woodier, mid-forward) voicings. 🛠️ Key Schematic Sections to Study
