From the vendor

NOTE: Does not come with ribbon cables. They're hard to accurately strip and we've wasted quite a few trying. We'll try to source some short ones. Prepare for the total and utter destruction of your tone. We've had the HellGazer in store for years now, but it was time to update it for an easier, more tweakable build. Take a look into the fiery depths of sonic hell. A two-fronted assault on your sound, with a full-on filthy fuzz on one side into a pushed-to-oblivion overdrive on the over. The right had size fuzz (Soda) goes from filthy to just plain ridiculous. There's an optional toggle switch to add in some screeching chaos, and a second to flip the orientation of one of the transistors to give you a piercing octave-up in the signal. Left hand overdrive (Cone Ripper) is loud. Like, really loud. The transistors are cranking out so much gain it sounds like your speaker is ripping to shreds. Nasty. There are optional toggles to increase the gain, making this an even crazier proposition, and to add some noise into the mix. We've also included an order switcher, but listen carefully.... this fuzz/drive combo works best in the standard Soda into Ripper configuration. No good shall come of reversing the order of things. No sir. After much experimentation, and being fans of the noisier end of things, we can honestly say that Ripper into Soda is not a winner. Save yourself a toggle switch. Honestly. If you do opt for the order switcher we've included LEDs which will indicate which side is first in the signal chain. Be aware that assembling the kit is MUCH more fiddly if you include this. The 4PDT toggle switch is a lot taller than the other toggles, and makes for awkward pot positioning and requires extra washers on the pots (included). If you're adding all the toggles you'll have to mount them without washers - sorry. 10mm spacing isn't enough to get those things in. No Biggy. Both circuits are independently switched, and the order when both are engaged is Fuzz (right) into OD (left) unless you include the switcher. This one is not for the faint hearted. Think NIN, MBV. Total WALL OF FUZZ. Footswitches and LEDs mount on separate daughterboards. Supplied with Lumberg jacks so they'll fit nicely above the pots. Pot spacing is 20mm so take that into consideration when choosing knobs If you want the PCBs without parts there's a link for that at the bottom of the page. Partial kit: PCBs, all board-mounted components (not footswitches), pots. Full kit: As above, plus footswitch and appropriate daughterboard/components for your selected bypass type (see Downloads section for details of those), jack sockets, DC socket, battery snap, hook-up wire, LED. Enclosure (pre-drilled) is available as an option with full kits, and will not take a battery. Knobs are not included. Builds are only available with full kits including enclosures. Please choose appropriate knobs. Inspired by: Shoe Gazer Difficulty: Hard PCB size: 82 x 45mm Knobs required: 4 Enclosure: 1590BB Download the INSTRUCTION PDF
