Description

feedback booster pedal ZVEX Super Hard On – Big City MusicThis is the perfect preamp pedal. The "Crackle Okay" volume knob is a negative feedback control styled after classic 60's recording console inputs. (They crackled when adjusted too.) Most vintage guitars suffer from steadily deteriorating magnets in their pickups, since permanent magnets aren't really forever. The Super Hard On's input impedance is so high (>5 Meg) that it refuses any current flow from your pickup maintaining the most magnetic field

This is the perfect preamp pedal. The "Crackle Okay" volume knob is a negative-feedback control styled after classic 60's recording console inputs. (They crackled when adjusted too.) Most vintage guitars suffer from steadily deteriorating magnets in their pickups, since permanent magnets aren't really forever. The Super Hard-On's input impedance is so high (>5 Meg) that it refuses any current flow from your pickup... maintaining the most magnetic field around each string, so you can hear exactly what your pickup sounded like the day it came off the winder. The ouput level can exceed 8 volts peak, and when it finally distorts, the wave is shaped like triode overload, not fuzz. 

It's so transparent no one will be able to tell you're using a pedal. Perfect for making the most of a classic amp and guitar, because it simply makes your guitar bigger and pushes the amp harder, causing natural overload. This sound can be the solution to the 'disappearing guitar' effect you get sometimes on stage when you stomp on your distortion and sound weaker. When cranked, it sounds much louder than a fuzz or distortion under stage conditions. 

Like all Z. Vex designs, current flow is low in this circuit (less than 2mA), enhancing battery life. The circuit board is hand-cut and soldered with the critical component, a BS-170 mosfet transistor, placed in a socket for easy user replacement should it be necessary. Your dealer can provide you with a free replacement transistor upon request. 

The box is hand-drilled using no petro lubricants, and hand painted so that every box is unique. Knobs are Harry Davies, made with the same molds they've used since the fifties. Each effect is hand dated and signed by Zachary Vex. 

WARNING: The very high input impedance of this pedal can cause strange reactions (sometimes mildly pleasant and/or arousing) when used with a vintage 'junk' (read 'cool') guitar. The solution is to simply lower the 'crackle okay' gain knob a little or leave the guitar volume wide open. Each Super Hard-On is unique in it's reaction... you may have to try a few till you find one that perfectly matches a really strange guitar. They are optimised for the major brands. Any problems will only occur at the highest gain settings with an unusual guitar. 

The Super Hard-ON uses a very sensitive transistor, with some early versions mounted in a socket. During 2000, I installed a protection circuit to prolong the life of these transistors and I've seen no failures since. If you have a problem with an older unit, feel free to contact me, or you may purchase transistors inexpensively from 1-800-DIGIKEY where they are sold as part number BS170P-ND. You must follow proper static handling procedures to install the part... write to me for instructions at and i'll set you up. Newer SHO units have a diode protection circuit to keep the transistor from blowing. Please contact for information about updating your older SHO. To protect your SHO's transistor on older units, please turn the unit off before unplugging the cords. On SHO units produced during 2000 and beyond, the battery switching jack has been moved to the output jack closest to the front of the unit (closest to the J. Myrold signature). Please unplug from this jack to preserve battery life.

A Beta Worth Rooting For
Format: Kindle
In Spare, Violet Fox flips the omegaverse on its head, giving us a Beta heroine determined to make her mark. Joining the Beta Trials to support her sick father, she's thrown into a pack that doesn't want her, especially the possessive Alphas. But here's the twist: their sweet Omega turns out to be her scent match. Cue the angst, forbidden tension, and a slow-burn romance that will make your heart ache in the best way. Violet Fox delivers an emotional, refreshing take on the genre, proving Betas aren't "spares." They're stars.

Beta, Alpha, Omega oh my!
Format: Kindle
Omegas are precious and given to Alphas & their packs... but the Betas want in too. To this end, the Beta government is rolling out its trial of assigning a Beta to each Alpha-Omega pack. But forcing a Beta into a pack where they are not wanted will not end well... Of course, no one expected the Omega to fall for the assigned Beta. Great read and cliffhanger

A familiar story, just with…..less.
Format: Kindle
So, as other reviewers make clear, this is very similar to Pack Darling and The Beta. It’s much closer aligned with The Beta, in plot and maybe more like Pack Darling with characters. That being said, I don’t hate this…..but it wasn’t great either. It’s both books mentioned but just….less. Less angst, less emotion, less feeling. The plot feels very half fleshed out, and the “bad guy” feels underwhelming. I didn’t really feel any real emotions from and of the male leads, except maybe Oliver. The others fell sorta flat for me. And Mika makes herself out to be this big bad ass straight outta training and then we never see it from here again with the one fitting room incident as the exception. SPOILER: The whole, “Oh, I’m actually probably an Omega, but I don’t wanna be but I do actually wanna be but no one can ever know my secret that I do nothing to hide “ thing fell so flat. She never commutes to believing she was secretly an omega, but also mentions her “secret” a lot. It just felt so manufactured. I’m intrigued enough to read part 2 and see how the author closes everything out, but this is not one I’ll recommend or ever come back to.

Fantastic writing and non-stop action
Format: Kindle
This is a promising, fantastic beginning to what will be a 4-book series. Some readers may be content to read only the first 2 books, but I think you'll find that the story is so good that you'll want to keep reading books 3 and 4. Book 1 is about omega Elvana's introduction to the "Starling" brothers and their search for another missing person, Kelly. It's a bit of a rocky start, with deception and betrayal a key element. Hardly an auspicious beginning. Each member has their own path and purpose in the pack. Their interactions and the resulting narrative are so well-written that I found it difficult to put down. There is a cliffhanger that will have you reaching for book 2 as you finish, so make sure you have it on hand.

Fun read
Format: Kindle
I'm not really into mafia books but I love Roxy Collin's other series so I decided to give it a try. It had the same great romance, spice, swoon-worthy characters and exciting plot that are her signature. Arben was my favorite, although it was a bit sudden how quickly he changed from ignoring her to wanting to be pack. There were almost too many twists/layers of lies to keep track of but I'm looking forward to reading the other books. The only thing that detracted from the story for me was the need for a bit more proofreading. It was mentioned that Kelly is a female and male at different points, leading me to think she changed her mind at some point about the character's gender but didn't go back and edit it to align in all places. Like another reviewer pointed out, step siblings are different than half siblings. They are incorrectly referred to as step siblings because they (allegedly) share the same biological dad. There are a few other typos as well but those aren't a big deal.
