JFET (jay-fet) is a boost pedal rooted in my love of the JFET transistor, long-loved in the world of audio for its similarities to vacuum tubes. As always for 29 Pedals it’s a ground-up design, from a blank sheet of paper, an effort to elevate the humble boost circuit to something refined and tonally enhanced.

The JFET circuit has three modes, N for “normal,” where a typical boost might sit in terms of frequency response, almost a treble boost but not quite. “F” adds a little more weight, and “X”, my preferred mode. “X” mode flattens the circuit all the way down to below 10Hz, giving you an incredible feeling of weight without sounding like additive EQ. The extension in the frequency response also tightens the phase and gives you an incredible, solid feel. The L control sets the level, it’s a fader after the boost circuit and before the output driver. This means the gain of the first stage is set, and you can use the fader to set the level into the output stage, so THD, hair, and tone remain the same throughout the travel. The output driver after the fader ensures that the output impedance remains consistent. JFET makes about 19dB of gain.

JFET can be used after a buffer or input driver (like EUNA), and also can function as an always-on input driver at the beginning of the board. It sounds great following EUNA and also stacked with FLWR and OAMP. It will drive heavy loads and has high-headroom, making it equally happy at the end of your board. The same WHATEVER power input and relay-based switching as our other pedals, and instant-bypass whenever power is removed.

Would recommend for casual show.
Color: 8405-Blue
It is very nice, I have many watches, but this one is the main one I use for casual wear. One thing I do not like: After about two days of either use or not use, the time gets off, by a couple hours but you can put it back pretty easily. And the "day display" on the watch never stays correct due to the fact that every month doesn't have 31 days in it. But other than that, it is a great watch for show, not to keep track of time.

Money Well Spent
Color: Silver Face Brown Band-G8408
I love this little watch, I can count on it every time one of my $10,000 watches stops working. The thing just sits in the drawer and waits for me, I was going to give it to a small child as a gift. I changed my mind only because it's good to know I have a dependable watch somewhere. I guess I'll have to pay attention to the battery at some point but I will change the battery and not just toss the watch..

A little disappointed.
Color: Silver Face Brown Band-G8408
The watch looks good but it stops running at times and if I move it around it starts back up. Been running okay for over a week now. Band is not as nice as it looks in the pictures, cheap looking. Will work for now.
