Patrick Pfeiffer, whom we interviewed back in June of '06, is offering two bass clinics designed to improve your groove.
The Philadelphia clinic is a two-hour free event at Bass Specialties (2846 Street Rd, Bensalem, PA. 215.244.4079 for details) on February 24th, 2007.
The clinic in New York City is an all-day for pay affair (10:00 AM to 7:00 PM) on March 24th, 2007 at AM Studios, 251 W. 30th Street - 4th Floor (between 7th & 8th Avenue). Tuition is $395/person.
Here's the PDF flyer with all the details. If you're fortunate enough to attend either event, please chime in on the forums and let us know about it.
