Includes the following modifications:

1. AC coupled VCF audio mixer inputs
Coupling film capacitors are added in series with audio mixer inputs 2-5 in the VCF section. PCB traces are cut to facilitate. This is a common modification performed on most TTSH, and many Arp 2600s. The change is reversible by removing the capacitors and installing jumpers in their place. Benefit: removes +5V DC offset present in VCO Sawtooth and Pulse/Square wave outputs. Improves performance of VCA by removing "thumping" effect.

2. Linear tracking improvement to Lag Generator
LM301 Op amp in Lag Processor is replaced with TL071. This is considered a standard fix that has been applied to most TTSH, and many ARP 2600s. The change is reversible by installing the LM301 instead. Benefit: improves tracking performance such that lag can be applied to KBD CV without affecting pitch accuracy.

3. Electronic Switch control input rerouted to External Clock In

The clock source connection for the Electronic Switch is re-routed to the tip pin of the External Clock In jack. When nothing is connected to this jack, the Electronic Switch functions normally. When an external clock source is connected to the jack, the Electronic Switch will track that source same as the Sample and Hold. (The Electronic Clock runs as normally and does not track external clock sources). Benefit: adds functionality to the Electronic Switch, such as gate division, or sub-oscillation.

4. Gate Boost (conditioning) with Trigger Generation

The Fuzzbass Gate Booster PCB is embedded, allowing conditioning of external gate sources and derivation of a trigger impulse. Benefit: allows just about any gate source to drive the TTSH envelope generators, and permits ADSR retrigger (so long as the Midi-CV interface connected supports it). The Gate Booster is inserted into the internal gate bus via a trace cut on the main PCB. Gate signals can reach the booster via the KBD GATE header, or the Gate In jack. Trigger output is connected to the Tip Normal pin of the Trigger In jack.
