Supro USA 1310 Tremolo Tube Emulated Guitar Effect Pedal Demo

Demo: May have minor cosmetic scratches/scuffs. Noteworthy blemishes will be pictured and described. Works as it should.

The Supro Tremolo is an analog stompbox designed to recreate two of the most desirable vacuum tube based modulation effects found in American amplifiers of the 1960's. The Supro Tremolo pedal's AMPLITUDE / HARMONIC switch allows the musician to choose between these distinctly different, vintage effects. AMPLITUDE mode provides the traditional swampy, tremolo sounds generated by bias modulating the power tubes in the original Supro amps. HARMONIC mode provides the psychedelic tones of Leo Fender's brownface and blonde amps from the early 60's. We've implemented Leo's unique 'harmonic tremolo' effect within the output stage of the pedal to create an amp-like modulation experience.

The Supro Tremolo pedal features pre-amp and power amp sections, with an actual output transformer deployed to recreate the magnetic saturation and coloration of the original vacuum tube based effects found in these historic amps. Along with the standard modulation controls for speed and depth, the Supro Tremolo also features a gain circuit that allows the musician to overdrive the output stage, right where the modulation effects are created. The GAIN control sets the amount of preamp gain in the pedal. As you turn the gain up, the power amp circuit will gradually be pushed into overdrive. This control gives you a wide range of sounds from clean to grind, with magnetic saturation occurring as the power section is pushed into overdrive. As you crank up the gain, the overall output level of the Supro Tremolo is automatically compensated in order to maintain consistent signal level. This allows the musician to use the GAIN control to alter the texture of the modulation effects without an overwhelming increase in audio output level.

SPEED and DEPTH controls determine the rate and amount of modulation present in the effect. An industry-standard TRS expression pedal can be used to control the speed of the Supro tremolo. When an expression pedal is in use, the on-board SPEED knob is used to set the maximum value. The rate of modulation is indicated by the pulsing LED status indicator. All Supro pedals are assembled in Port Jefferson, NY, USA, featuring custom-tooled, anodized, brushed-aluminum enclosures, 9V battery or AC powered operation, rear-mounted metal jacks, easy-access side-mounted battery drawer and studio-friendly, noiseless (click-free) true-bypass switching.

Clean prints
Style: WF-7840, Set: DUAL TRAY (500 sheets)/FAX/ADF/PRINT/COPY/SCAN
Works well but a little slow. This could be only my internet connection speed through my router. I thought the 11x17 paper would fit fully inside one of the trays. It does not and hangs out as shown in the instruction manual which came with the unit. The initial ink cartridges are working well beyond their expected time.

wi-fi connectivity appears to be fixed! Yay!
Style: WF-7840, Set: DUAL TRAY (500 sheets)/FAX/ADF/PRINT/COPY/SCAN
Updated: Connectivity has only failed once out of may prints! Yay! 5 stars if this keeps up! LEAVE THE FIRMWARE ALONE NOW! Updated again: This latest firmware update is an improvement. Up to 4 stars now: The printer has worked 2 times out of the last 3 prints. That is better than never working. Killing the Epson task and unplugging/plugging the printer is still the fasted way to fix when connectivity fails. Updated again: Every frequent firmware update makes the connectivity WORSE. Now the printer FAILS TO CONNECT EVERY TIME I PRINT. Right now the printer is installing yet another update. The notification says the firmware update is under SETTINGS. Yes, true, but 4 layers down so I end up searching and scrolling back an forth with every update. Why is it that the most used features are buried in the menus. Coder's revenge, I guess. The connection fails, the connection fixer thing asks a bunch of stupid questions and won't go away. Is the printer on? Did you change your router? Then is fails and suggests trying more stupid stuff. It should say: Use Task Manager to kill the running Epson task. Unplug the printer, then plug it back in. In 5 minutes, you will have your print. How convenient. EVERY TIME I PRINT. I expect this or the next FW update will kill even that. This is a beautiful mechanical machine with idiotic electronics and firmware/software. Updated review: This printer forgets who and where it is about once a week. The printer is only 6 feet from the Wi-Fi router. I have to run the Connection Checker program, answer irrelevant questions, reset the router, blah, blah, blah - the robot version of a customer support call. Make sure you also have an HP or Brother printer in case you need something printed right away when it hangs up. You will end up with an extra copy once the Epson wakes up. This is getting old. My HP printer never does this. My two Brother printers never do this. Epson finally came out with a mechanical masterpiece that always feeds and never jams. Now Epson needs to work on their interface design. I never thought Epson Connection Checker would be on my most-used software list. ---------- Original review: I really like this printer. I am not a photographer and I don't print t-shirts. The WF-7840 prints fast and feeds paper without jamming. That is more than I can say about the Artisan 1430 as a general purpose printer. This is a big printer, but if you have room for it, it is a very nice machine. It does so much that you will need the help file to do much of anything, but it will be there somewhere. I printed all of June, July, and August and part of September on the starter ink cartridges. I only use it for color prints. I have 3 laser printers for B&W prints. The WF-7840 only has ink 4 cartridges instead of 6 like the 1430. I am very happy with my purchase.

Jobsite Workhorse
Style: WF-7840, Set: DUAL TRAY (500 sheets)/FAX/ADF/PRINT/COPY/SCAN
Have had previous models of this printer and they have always been solid. We use them in our office trailers on our construction jobsites and this new version works excellent just as the previous series did.

Excellent, as long as you don't update firmware
Style: WF-7840, Set: DUAL TRAY (500 sheets)/FAX/ADF/PRINT/COPY/SCAN
About 6 months in, and I am very happy with the performance of this printer. I loved that it collated multipage documents without being told to! I have denied every request for firmware updates, and I am pleased to report that remanufactured ink cartridges (pronounced "more affordable and just as good") work just fine. DO NOT UPDATE THE FIRMWARE. The updates only serve to make it impossible to use off-brand or remanufactured ink cartridges.
