Electro-Harmonix HOLY GRAIL MAX Reverb PedalThe Holy Grail Max from Electro Harmonix is a compact reverb pedal that features four different reverb algorithms: Spring, Hall, Plate, and Reverse. The algorithms were designed and tailored for the electric guitar, but work equally well with most instruments and voices. Controls are included for Time and Blend. The Time knob adjusts the reverb's decay when in Spring, Hall, and Plate modes. In Reverse mode, it regulates the length of time between

The Holy Grail Max from Electro-Harmonix is a compact reverb pedal that features four different reverb algorithms: Spring, Hall, Plate, and Reverse. The algorithms were designed and tailored for the electric guitar, but work equally well with most instruments and voices. Controls are included for Time and Blend. The Time knob adjusts the reverb's decay when in Spring, Hall, and Plate modes. In Reverse mode, it regulates the length of time between striking a note and the reverb fade-in. While in Plate mode, when Time is set to its maximum position, the reverb decay is over 30 seconds long, creating a lush reverb wash with each new note. A Blend knob adjusts the wet/dry mix. The unit is enclosed in a tough and compact die-cast chassis, and comes with a US9.6VDC-200BI power supply.

The Spring algorithm is a re-creation of the classic spring reverbs that are found in many guitar amplifiers. The Hall algorithm simulates the reverberations heard in large spaces such as concert halls and cathedrals. The Plate algorithm is an emulation of a metal plate reverb which was commonly found in high-end recording studios during the 1960s and '70s; it is a very smooth, tonally balanced reverb that works well on many different instruments, and especially on vocals. Reverse Reverb is an emulation of the reverse reverb trick commonly performed in studios. True bypass switching ensures your tone won't be affected when the pedal is bypassed.

Specifications:
- Spring, Hall, Plate and Reverse reverb
- 9.6DC-200 power supply included
- True bypass for maximum signal path integrity
- Compact, rugged die-cast chassis

Longest lasting toy in our toy box
Size: 6 in, Color: Blue
My German shepherd/Austrian shepherd mix destroys toys very quickly. This is his longest lasting toy that he actually uses and still has no visible signs of destruction.

my puppy shreds every "indestructible" toy I give to her instantly. she's had one for months and it is only missing a corner of it, so I bought a spare. it also smells like food. she loves it.

These were challenges for my aggressive chewers! Quality ingredients.
Pattern Name: Peanut Butter, Size: 6 Inch (Pack of 15)
My dogs absolutely love these and the hardness keeps them busy for a while. The package comes with various thickness of sticks. The thinnest ones only last for 5-10 minutes, but the thickest ones take 3-5 hours. The top end varies as it totally depends on the dogs' energy levels at the time. I'm not crazy about the smell of peanut butter and was happy to find these to be more woodsy with a faint peanut odor. My dogs get super excited as soon as they see the bag! My two dogs are different breeds, but both small to medium in size (32-40 pounds). I was worried about choking and the digestion of these. This is the second month and we haven't had a single issue.
