Hand Wired
Meticulously selected audio grade through-hole components mounted on especially designed eyelet boards ensure easy maintenance and modification. Observing “circuit constants”, every board is a “one-off”, unique to the amp.
Delta
Unleash your imagination with the Delta, a D-style amp that will give you everything from smooth and silky cleans to a wild, crushed glass overdrive. Pair it with a speaker cab that can handle its 100W of raw power and put the amazing three-dimensional sonic register of the amp and the guitar, front and centre of the mix.
A truly dynamic amp with a three-band EQ, two levels of boost and a cascading overdrive, providing a very wide and dynamic spectrum of tonal possibilities, suitable for all kinds of musical styles, from smooth jazz to hard rock.
Complementing the Delta’s classic analogue design with an onboard tube driven FX loop makes this an ideal pedal platform for the modern player using modern effects. Or go old school and use only the three-button footswitch and explore the possibilities with an amp designed for maximum versatility. Each stage is carefully designed to provide the player with the optimum signal and tone shaping control.

Effects Loop
Fully integrated tube driven effects loop for time-based effects in series or parallel and zero loss of tone. Preamp out and power amp in jacks allow for connection directly to a mixing desk. Can also be used as an attenuator.
FET and EQ
The integrated high impedance FET boost allows for unity gain of low signal sources or for adding a touch of distortion to the lead tone. The dynamic TMB tone stack allows the player to dial the amp in to a very broad, expanded tone palette.
Custom PCBs
Individually etched PCBs with ruggedised traces ensure cooler, noise free operation with the smallest components. Every PCB is inspected for any microscopic defects and is only integrated into the working amp when it is perfect.
Customised Pots
Custom taper pots ensure the optimum frequency response across the tone stack and overdrive channel. Precision modification of pots ensures the greatest transparency of tone between the clean and overdrive channels.
Handbuilt Cabinet
Finest quality, lightweight, air-dried, pine cabinet constructed with mechanically superior half-blind dovetail joints. Finished in the covering of your choice with the highest quality detailing you can expect for your requirements.

Tube Buffered Effects Loop
A fully featured FX loop, really two-in-one, partly inspired by the “Dumbleator” rack unit designed by Alexander Dumble. Modifications to the basic cathode follower design feature: a parallel, passive loop; a lower output impedance drive stage; selectable line and instrument levels; a linear Mix control for parallel side-chaining; a Bright switch for recovering high-end losses when using longer, higher capacitance cables to your effects pedals. The added Bypass/Engage switch allows you to bypass the loop circuits entirely.
Active Loop: SEND / RETURN
Type: series / parallel
The lower impedance modifications to the drive-side of the circuit ensures that time-based effects pedals receive a signal with a very low sound floor. The cathode follower is non-inverting, so all things being equal, the tone remains rich and full. Tube buffered effects loops are not typically “zero loss” but the fully integrated design of this loop means that if the Drive and Gain controls were set to unity gain, you wouldn’t know it was engaged if you hadn’t set the Bypass / Engage switch yourself. The Gain control can also be used to trim the signal level, (even without any jacks being plugged in) boosting or attenuating it. A handy little exploit if you want to drive the front end of the amp without waking the dead.
The Mix control can also be used to trim the level when the loop is in series mode but comes into its own when the loop is used in parallel for side-chaining effects with a remarkably linear interplay between the wet and dry signals. Great for instance if you want to dial in a little reverb for the room you are playing at the beginning of a gig. Larry Carlton would approve.
Passive Loop: PRE-OUT / PWR-IN
Type: series
This send and return signal is unbuffered and the PRE-OUT (send) jack is fed by the signal from the preamp and Master pot and the PWR-IN (return) jack is the return path for the signal directly onward to the phase inverter and the power section. This series, line level loop offers optimum signal and directly bypasses the cathode follower: straight out from the preamp, straight back into the power amp. The Master volume on the front of the amp controls the signal sent to PRE-OUT jack but further trimming can be achieved by hooking up a volume/expression pedal here. Inserting jacks in the passive SEND and RETURN ports disengages the active loop circuit.
