[15 oz (420 g)] After working my way through various competing processors (including other Boss and Roland products) that offered similar capabilities I had pretty much given up on finding one that suited my needs. The GT-1's combination of preset factory sounds, their ease of tweakability, variety of effects and ease of their tweakability offers a player a massive selection of tools to work with. Controls are easy to use and logical in how they are set up. Couldn't be more pleased.

[15 mA (9 VDC)] this is awsome

[1 kOhm] First, I love this item . I have a Roland GR55 now. When I have access to AC power, I have a ball with it.
But,
I busk in my town’s Main Street where AC power is not available. Granted, the SY-1 isn’t as sophisticated and the GR 55, but now I can expand my guitars palette of tones.

I had been searching for this item for months. All the typical outlets kept pushing their in stock dates forward in time. I even made a purchase of the SY-1 on eBay, only to have the seller cancel the sale for no apparent reason.
I searched again and saw it listed on B&H. It said it was in stock. I called and was told it was in inventory. A few days later it was in my hands .

Cannot Be too positive about my experience with B&H. They came thru..hands down.

I have shopped with them before, but now, they are my first go to place for music gear.

THANK YOU!!

[15 oz (420 g)] Small and does everything I need, love the sound

[1 MOhm] A must have for those who wanted to have versatile guitar sound, also good for background ambiance while playing strum guitar, inspire you to make more music.

[6 x 3.75 x 2.7"] If you just want to sit quietly in a house full of people who don't want to hear you shred get this.

[1 kOhm] Zoom knocks it out of the park with every product they make. I needed a volume pedal. This multieffects unit cost less than a volume pedal. Plus it gives me a looper, drum machine, and multieffects.

This pedal provides a studio quality effect unit for the price range. I don't play out live so I don't know what the noise level of this pedal is like under stage conditions. I also bought the Zoom MS-50G which is a higher quality pedal but not as fun. The MS1 has knobs and switches for effective realtime control.

It is very easy and faster to write and customize effects compared to the MS-50G. Both pedals are great.

[15 mA (9 VDC)] I bought this to replace other non-digital compression and eq pedals. I was not interested in calling up many patches. I try to get a McCartney sound and along with nylon flats on a Hofner this allows me to dial it in. I use the Bassman preamp, para-eq's, graphic eq, dbx 160 and MXR stle compressors. I created 3 different patches, tic tac bass, plinky but full bass and deeper bass. I play with two acoustic guitarists in smaller rooms so I use a small Gallien Krueger amp or a Markbass 12 inch combo. My only complaint is that none of the compression settings have any visuals showing gain reduction so it's all up to my ears. Sound quality is great. I haven't spent much time trying out the other patches but their Markbass patch impressed me on how close it was to a Markbass amp.

[-20 dBu] Impressive right out of the box. The possible combinations effects, amps, synths, etc... make this Boss a virtual limitless fountain of sound.

[-20 dBu] Exactly what we've come to expect from Boss/Roland. Pedal just works. Sounds good and built like a tank. Easy on batteries when you don't want to run power. Priced right.
