[5] Weinman has also been listed on About.com as an example of today's most important musicians under their definition of "guitarist" and was named one of Alternative Press Magazine's "10 Favorite Guitar Slingers".

[9][10] He later stated that "music saved his life" because it helped him to discover new ways of learning, make friends and it gave him a sense of purpose.

[11] Weinman attended Fairleigh Dickinson University in Madison, New Jersey where he first received a degree in psychology in 2000 and then in corporate communications, a field in which he worked for some time afterwards at a web company.

Calculating Infinity was also named one of "100 best rock albums of all time" by Kerrang magazine, who presented Weinman with a spirit of independence award.

[25] Ben Weinman cited John McLaughlin, Robert Fripp, Greg Ginn, Stevie Ray Vaughan, Marty Friedman, and Steve Vai as his biggest influences.

[26][27][28][29] Weinman acknowledges Apocalypse by McLaughlin's Mahavishnu Orchestra as the album that changed his life, stating that "It was a huge part of what led me to make Dillinger".

[30] The guitarist cited experimental band Mr. Bungle as his biggest influence in terms of eclecticism and the irony of his music, as well as in managing tours.

Weinman has been seen using a variety of amps in the studio, ranging from a Bogner Uberschall, a Laney GH50L and a Marshall JCM, but he mainly uses Mesa/Boogie Triple Rectifiers and a Mark V for live performances.
