LM308 Op-Amp Distortion

The LM308 Op-Amp Distortion by Hartman Electronics is a guitar pedal that offers two modes of distortion inspired by the edgy, modern styles popularized by punk, new-wave, and college-rock bands of the late 70's and early 80's. The pedal features a diode-clipping stage for classic distortion and crunch in the first mode, and an asymmetrically-clipped overdrive in the second mode, emphasizing transparency and medium gain. Technical Specifications: \- 3PDT Heavy-duty True-bypass switching \- Hi-intensity LED Indicators for ON/OFF and Distortion type (A/SYM) \- Plated-thru-hole printed circuit board (PCB) construction \- Premium quality Switchcraft jacks and Alpha potentiometers \- Ultra-quiet 1% metal-film resistors throughout \- Hi-fidelity tantalum, silver-mica, and film capacitors \- LM308AH (round, metal-can) op-amp \- Blackened-bronze powder-coat finish, Crème knobs \- Power: <30mA @ 9VDC \- Dimensions: Width: 4.9" (125mm), Height: 2.1" (54mm), Length: 4" (101mm) The pedal allows for on-the-fly selection of distortion modes via a stomp switch, providing players with versatile tonal options. It is designed to maintain the sensitivity to player pick-attack, palm-muting, and pinch- harmonics, while also offering increased transparency, headroom, and dynamic response in the overdrive mode. The LM308 Op-Amp Distortion pedal is built with high-quality components and a specific LM308AH op-amp to deliver the desired distortion and overdrive tones. The pedal's construction and design aim to provide a reliable and expressive tool for guitarists seeking classic and modern distortion sounds.



BC108 Fuzz

The Hartman BC108 Silicon Fuzz is a faithful recreation of the early Silicon transistor Dallas Arbiter Fuzz Face circuit, featuring genuine BC108 NPN Silicon transistors. The pedal is housed in a rugged metallic silver powder- coated aluminum enclosure and includes modern amenities such as true-bypass, on/off LED, and a 9VDC-in jack. Key Specifications: \- Genuine BC108 NPN Silicon transistors \- Quiet carbon film resistors \- Heavy-duty true-bypass switching \- Rugged metallic silver powder-coated aluminum enclosure \- ON/OFF LED \- 9VDC input jack \- Power consumption: <30mA @ 9VDC (positive ground) \- Dimensions: Width: 4" (101mm), Height: 2.1" (54mm), Length: 4.9" (125mm) The tonal variation among BC108s of similar gain is relatively mild compared to their Germanium predecessors, with leakage an order of magnitude smaller. The pedal exhibits workable cleanup, dynamic voicing, and smooth decay. An external bias control is standard on all units, allowing for ultra-smooth or crisper fuzz, and even the trademark crackle, spit, and grind of "starved" Silicon. The BC108 Silicon Fuzz is designed to provide a musical sounding distortion pedal, suitable for various musical styles and applications.


The 8va by Hartman is a faithful recreation of the Tycobrahe Octavia, a seminal effects pedal from the 1970s. It replicates the exact signal chain of the original Tycobrahe, delivering classic tones such as raucous, searing fuzz, blooming, crystalline upper octaves, and space-age ring-modulation effects. The pedal features heavy-duty true-bypass switching, ON/OFF LED indicator, and an external 9VDC power in jack. It consumes less than 30mA at 9VDC (positive ground) and has dimensions of 4" (101mm) in width, 2.1" (54mm) in height, and 4.9" (125mm) in length. The pedal is meticulously grounded and shielded in a rugged metal enclosure to ensure quiet, RF interference-free operation. It also includes a specially designed input level trim to accentuate the octave character of the sound. The pedal is made in the USA, ships with a new 9V Carbon Zinc battery, and carries a 1-year limited warranty.
