Velcro is attached to the back. Otherwise, it is clean with no scratches. No box or other accessories are included. Honestly, I thought it was the best because you can perfectly create the sound you're aiming for with just one unit. Moreover, you can pursue each setting without compromise. There is information and sound sources available online, so please check them out. The following is a quote: It is possible to create a very wide range of sounds, from clean boost to classic rock, heavy metal, and fuzz. This type of all-in-one pedal tends to be a jack-of-all-trades and master of none, often failing to produce a good sound, but this Odyssey is in a class of its own. It is set up to produce a sound that can be used without problems with any guitar or amp, regardless of the setting. It is equipped with a powerful EQ circuit that can boost or cut 18dB, and allows you to select pre/post, which determines whether the EQ circuit is connected before or after the drive circuit. It also has a mode that bypasses the drive circuit. The Odyssey can handle everything from classic TS-type pedal drives to open and very wide-range transparent drives, amp-like drives that are very faithful to touch nuances, and even saturated fuzz sounds. ●DRIVE CIRCUIT ・DRIVE Adjusts the gain level. ・TONE Low-pass filter. Adjusts the high frequencies within the circuit. ●EQ CIRCUIT ・BASS 18dB cut/boost of low frequencies. ・TREBLE 18dB cut/boost of high frequencies. ●LEVEL Adjusts the output level. ●C1・C2・C3 ・C1 Target clipping ・C2 Asymmetrical clipping ・C3 2-stage clipping ●X2・X1・X5 ・X2 Doubles the input level and boosts the gain. ・X1 Outputs at the same level as the input. ・X5 Multiplies the input level by 5. ●PR・EQ・PO ・PR: Places the EQ CIRCUIT before the DRIVE CIRCUIT. Ideal for amp-like and saturated drive sounds. ・EQ: Clean boost mode. Throws the DRIVE CIRCUIT and clipping. ・PO: Places the EQ after the DRIVE. ●Internal dip switch Allows you to select the bypass behavior when the power is turned on.
